Different Types of Wrenches
Here are some of the different types of wrenches from which you can choose
A box end wrench (or closed) is used where there is room to place the wrench mouth around the fastener. Box end wrenches are available in 6- and 12-point versions to match the number of sides on the fastener. Hexagon fasteners have 6 sides, or points, and are the most popular.
This type of wrench is used for turning fasteners in locations where a box end wrench cannot encompass the fastener. It's can also help loosen fasteners.
A combination wrench is a versatile tool that masterfully combines two types of wrenches into one. On one side, it features a box-end, a closed loop that expertly grips hexagonal or square nuts, ideal for those tough-to-loosen nuts. On the flip side, it has an open-end, a U-shaped design, perfect for swiftly unscrewing the nut once it's loosened.
The dual functionality of a combination wrench makes it a go-to for many DIY enthusiasts and professionals. Available in both metric and standard sizes, combination wrenches cater to a wide range of bolt dimensions.
An adjustable wrench is also sometimes called a crescent wrench. Adjustable wrenches can be used on a variety of fastener sizes. The disadvantage is that it is less stable than a fixed-size wrench and can easily injure you or damage the fastener. An adjustable wrench should be used only if the correct size wrench is not available.
A torque wrench is a precise tool for controlling the force on a bolt, preventing over- or under-tightening, crucial for sensitive tasks like engine work. Similar to a socket wrench, torque wrenches have a head, adjustable socket, rotating handle with measurement marks, and a locking nut at the bottom.
To use a torque wrench, loosen the bottom nut, adjust the handle to the needed torque level (in lb-ft, lb-in, or Nm), then attach the socket and turn to tighten or loosen the bolt. The wrench signals when reaching the set torque. Always reset it to the lowest setting after use for accuracy.
A socket wrench, also known as a ratchet wrench, is a must-have tool for turning fasteners with precision and ease. Socket wrenches fit over the fastener, making removal easier and safer than with other wrenches.
The magic of a socket wrench lies in its ratcheting system attached to the handle. This clever design allows you to tighten or loosen nuts and bolts by simply pushing or pulling the handle, without needing to remove and reposition the wrench after each turn. It's especially handy in tight spaces where movement is limited. Sockets come in standard and extended depth; extensions are available to make removing fasteners easier.
The pipe wrench, ideal for soft piping such as black pipe, is a key tool with an adjustable jaw and sharp teeth for a strong grip on various pipe sizes. It comprises a handle, adjustable nut, fixed jaw, and adjustable jaw.
Use it by holding the end of the handle for leverage and adjusting the nut to fit pipe sizes—clockwise for smaller and counterclockwise for larger pipes. The adjustable jaw on pipe wrenches moves up and down for easy positioning. Longer than other wrenches, the pipe wrench provides extra leverage and grip, perfect for securing or loosening pipes effectively.
The Allen wrench is an L-shaped wrench that is easily recognizable by its hexagonal head, designed to fit into bolts with hexagon-shaped sockets. An Allen Wrench stands out for its two hexagonal ends, each offering distinct advantages.
When you insert the wrench vertically into a bolt, you'll have less leverage, making it slightly harder to turn but easier to reach tight spots. However, for really stubborn bolts, use the wrench at a 90-degree angle to the nut. This position gives you more leverage, making it much easier to loosen tight bolts. Remember, the longer side of the wrench provides more leverage.
The strap wrench is a unique and versatile tool, perfect for gripping and turning objects without causing damage. Unlike traditional wrenches, it uses a strap, usually made of rubber, to create friction and securely hold objects. This design ensures that delicate surfaces stay scratch-free, making it ideal for sensitive materials.
Most strap wrenches come with handles for a sturdy grip, but some are made to attach to the square drive of ratchet wrenches. Its adaptability to any size makes it not only useful for professional tasks but also handy for everyday household chores, like opening tight jar lid.
The pedal wrench is a specialized tool designed for cyclists and bike mechanics. This type of wrench is used specifically for attaching or removing the pedals from a bicycle. What sets the pedal wrench apart is its thin profile, which allows it to slide easily between the pedal and the crank arm, where space is often tight.
Usually, one end of the pedal wrench is angled, providing extra leverage to loosen or tighten the pedals effectively. The other end is typically flat, making it convenient to use in different positions.
Main Uses of Adjustable Wrench
Plumbing
One of the best uses of adjustable wrenches is definitely plumbing. Plumbers all over the world use adjustable wrenches when installing pipes of different thicknesses because they are so flexible. For example, the hex bolt fittings for sinks are larger in size, while those for bathtub faucets are smaller. Adjustable wrenches are therefore ideal for acting on nuts of different sizes to tighten or loosen them.
Auto Mechanics
Almost all auto mechanics have an adjustable wrench. They are more advantageous than other wrenches in certain auto repair jobs. The uses of adjustable wrench are getting into smaller areas and handling nuts that are placed in difficult locations. Socket wrenches can serve the same purpose, but sometimes an adjustable wrench will provide better grip and more torque to remove a particularly difficult nut or bolt head. Some cars have awkward hand spaces where a regular wrench simply won't work, so adjustable wrenches are great in these situations.
Furniture
Self-assembled or self-made furniture sometimes requires some kind of nuts or bolts to be installed. The great thing about adjustable wrenches in this case is that they help you save time. Carrying around dozens of wrenches and trying to figure out which one fits can be a waste of time. Using an adjustable wrench instead will mean simply matching it to the nut or bolt head, adjusting it to the right size, and then tightening it. It eliminates the need for most other tools and minimizes the need to lug a heavy toolbox from one place to another to assemble furniture.
Benefits of Using Combination Wrenches
One of the primary advantages of combination wrenches lies in their dual-purpose design. They feature both an open end and a closed end, each serving a distinct purpose. The open end is ideal for swiftly turning fasteners in confined spaces, while the closed end delivers a firm grip and extra torque for stubborn bolts.
Varied Sizes and Durability
Combination wrenches come in a range of sizes, ensuring suitability for diverse applications. This versatility minimizes the need for an extensive collection of individual wrenches, saving both space and resources. Moreover, their typical construction from robust materials guarantees a long-lasting, reliable tool for rigorous tasks.
Perfect for Automotive Repairs
For automotive repairs, combination wrenches are indispensable. They excel in tightening or loosening nuts and bolts within engine compartments, underneath vehicles, or in tight, hard-to-reach spaces that may challenge other tools. Their slender profile and maneuverability make them an excellent choice for mechanics and car enthusiasts alike.
Ideal for Home Improvement and DIY Projects
Combination wrenches are equally valuable for home improvement and DIY projects. Whether assembling furniture, addressing plumbing issues, or tackling household repairs, these tools prove versatile enough to handle a wide range of tasks. They allow for precise application of force without damaging fasteners.
If you're interested in acquiring a reliable set of combination wrenches, consider our combination spanner/wrench set. It offers a cost-effective means to equip yourself with a comprehensive set of combination wrenches suitable for a multitude of situations.
General Safety Tips When Using Wrenches
Use the correct wrench for the job - pipe wrenches for pipes, plumbing fittings, and general-use wrenches for nuts and bolts.
Discard any damaged wrenches (e.g., open-ended wrenches with spread jaws or box wrenches with broken or damaged points).
Select the correct jaw size to avoid slippage.
Wear safety glasses or a face shield (with safety glasses or goggles) where there is a hazard of flying particles or falling debris.
Position your body in a way that will prevent you from losing balance and hurting yourself if the wrench slips or something (e.g., a bolt) suddenly breaks.
Use a box or socket wrench with a straight handle rather than an offset handle when possible.
Ensure that the jaw of an open-ended wrench is in full contact (fully seated, "flat", not tilted) with the nut or bolt before applying pressure.
When turning with an adjustable wrench, the direction of the turn should be against (towards) the permanent jaw.
Make sure that the teeth of a pipe wrench are sharp and free of oil and debris and that the pipe or fitting is clean to prevent unexpected slippage and possible injuries.
Apply a small amount of pressure to a ratchet wrench initially to ensure that the ratchet wheel (or gear) is engaged with the pawl (a catch fitting in the gear) for the direction you are applying pressure.
Support the head of the ratchet wrench when socket extensions are used.
Pull on a wrench using a slow, steady pull; do not use fast, jerky movements.
Stand aside when work is done with wrenches overhead.
Make sure adjustable wrenches do not "slide" open during use.
Keep tools well maintained (cleaned and oiled).
Clean and place tools and wrenches in a toolbox, rack or tool belt after use.
Tips on Maintaining and Taking Care for Your Wrench
Storage When it comes to the maintenance of the wrenches, the first thing everyone considers is the ‘toolbox’. Organizing spanners in a convenient way is the first thing in spanner maintenance. If you buy a single spanner, then you might have to buy a separate toolbox. However, if you buy a set of spanners, then it might come in a toolbox.
Make sure to place your spanners in a dry place to protect them from moisture. Not only store your tools, but you need proper maintenance of the tools. Rather than storing them, make sure you are organizing them in a proper way. When you organize your tools, then you are more likely to find a tool with ease.
Lubrication for Spanners When it comes to wrenches and other hand tools, lubrication is an essential part. With the help of lubrication, you can use your spanners and other tools with ease. Ensure you apply good machine oil for a particular tool to get all the moving parts. Oil removes the barrier against moisture getting to the part of the spanner.
Vehicle metal polish can be used for especially chrome-plated spanners. If you regularly apply metal polish, then you can prevent your spanners from corrosion.
Inspect Spanners Properly Ensure to check wrenches/spanners and other tools before using them because a broken tool can damage the fastener as well. Even you can get injured from a damaged tool, so make sure to inspect spanners well before using them. If any tool is cracked, then try to replace it instead of using it.
Tools are more prone to rust and need proper care. So, ensure to oil your tools daily, or you can use silica gel packs. Silica gel packs can prevent rusting.
Cleaning Tools After every use of wrenches and other hand tools, make sure to clean them properly. This process will take less time and save money and time that you might require to invest during repairing. You can simply wipe off dust with the help of a simple cloth or rag. Clean dust from tools to avoid corrosion.
Maintenance while Using Make sure to use the right size of the wrenches for the fastener. A spanner of large size can damage the bolts or fasteners. It can also damage the spanner profile.
If you are trying to remove or fit the fastener, then don’t use brute force because you may get hurt. If the fastener is stuck, then you can use penetrative oil. Don’t use a hammer to hit the spanner because it can damage the spanner, and even you can get hurt.
Use Manuals Every hand tool contains a manual with it, so make sure to read all the instructions before using, cleaning, storing, and maintaining. Manuals are very important for all hand tools ranging from small to large.
