Wrenches are made in various shapes and sizes and are used for gripping, fastening, turning, tightening and loosening things like pipes, pipe fittings, nuts and bolts.
A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.
Unlike pliers, wrenches generally do not have pivoting jaws (an exception is the sink wrench). … Wrenches are almost always a better tool than pliers for loosening and tightening nuts and bolts because they provide greater torque than pliers and are less likely to round or damage fasteners.
Wrenches. Ratchets and sockets are among the different types of wrenches designed for specific tasks. They perform the same functions as a conventional wrench — tightening and loosening fasteners. … Also, since a socket fits completely around a fastener, it’s less likely to slip off than some types of wrenches.
- Choose the right wrench for the job. Always choose the right size wrench jaw size that corresponds to the fastener you are looking to tighten or loosen. …
- Always Pull. …
- Never add leverage with another item. …
- Never hit a wrench with a hammer. …
- Only buy quality.
A spanner is a type of adjustable wrench. Outside of North America, spanner is just another word for “wrench.” If Americans want to ruin something, they “throw a wrench into it.” British people “throw a spanner in the works.”
A small set may have six to 10 wrenches, ranging in size from perhaps five-sixteenths to one inch. Standard wrenches are sold in sixteenth-inch increments up to one and a half inches (and in metric sizes, too, of course).
Always pull, rather than push, a wrench for greater control and balance. That way, if the nut or bolt should suddenly loosen, you’re less likely to go flying. Never try to get more torque from a wrench by using a cheater bar or other device to extend the leverage.
Can adjustable wrenches be used exactly like open ones, by flipping them over for a new swing? No. Adjustable wrenches should be placed on the nut so that the pulling force is applied only to the fixed jaw-side of the wrench. 7.
Proper use of diagonal cutting pliers: For work involving cutting and skinning wires, cutting and removing pins, nails and other fasteners.
A socket wrench is most commonly a handle with a 90 degree ratchet, along with a set of cylinder shaped “sockets” of various sizes. The sockets fit onto the ratchet by way of a square nub. You can set the ratchet to either tighten or loosen, then keep the socket in place on the nut while you turn the handle.
A ratchet is a mechanical device that only allows movement in one direction. When it is equipped onto a wrench, it allows the user to set two turning directions: one where the wrench head is fixed and one where it spins freely. … Wrenches that indicate and control torque are equipped with ratchets.
Can you use regular sockets with a torque wrench? – Quora. Absolutely as long as you have the right size socket for the size of the drive on the end of the torque wrench…
A pipe wrench has two serrated jaws that are tightened and dig into the pipe for grip. The top serrated jaw adjusts up and down to fit different size pipes. The unique feature of a pipe wrench is that the teeth will only grip when turning the wrench in one direction (see above), so it almost acts as a ratchet wrench.
The purpose of a wrench is to turn a bolt head or nut. Selecting the appropriate wrench depends on the fastener’s design and size. It can also depend on how difficult the fastener is to reach. Wrench types include open end, combination, adjustable, and Allen.
One reason people slip with the wrench is it’s not square with the work. This alignment will put the handle of the wrench in the correct position. But if you push the wrench from an odd angle, you’ll push it off the fastener. That’s another reason people slip with the wrench.
Torque or turning effect due to a force is maximum when r is maximum. We prefer to use a wrench with long arm because when the length of the arm(r) is long, the force (F) required to produce a given turning effect ( x ) is smaller. Hence, a nut can be unscrewed easily.
The monkey wrench is a type of adjustable wrench, a 19th century American refinement of 18th-century English coach wrenches. … The term monkey wrench is also sometimes used loosely, usually by non-tradespeople, to refer to the pipe wrench (owing to their broadly similar shapes).
On top of these standard tools, there are over 40 different wrenches on the market. In this article, we’ll review 40 different wrenches and their uses. From adjustable wrenches to fire hydrant wrenches, this article discusses all the varieties of wrenches available.
It does not require a VR headset.
A slogging spanner has a thick end that is designed to be used with a hammer to tighten fasteners, such as nuts and bolts to a precise torque. Slogging spanners are also ideal to untighten fasteners which are stuck, as they pass high levels of force and vibration through to the nut or bolt when hit with a hammer.
Take the diameter of the bolt, and multiply by 1.5. This calculation and conversion factor is valid for either metric or standard bolt sizes. The resulting number will be the size of the wrench you need to adjust the bolt properly. For example, If your bolt measures .
Standard Combination Wrenches (1/4, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1) Metric Combination Wrenches (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) Standard Flare Nut Wrenches (3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 7/8) Note: Each wrench may combine two sizes.

“Don’t have a wrench? Try a pair of pliers!” (Wowee, thanks.)
- Use a screwdriver with a head that fits snugly in the screw head.
- Put the palm of one hand on the back side of the screwdriver handle, and wrap your other hand around the handle ready to twist.
- Push the screwdriver as hard as you can with your back hand into the screw, and twist with your other hand.
- 1) Only use quality wrenches. …
- 2) Match your wrench size to the job. …
- 3) Always pull, never push. …
- 4) Keep wrenches clean. …
- 5) Never strike a wrench with a hammer. …
- 6) Do not attempt to add leverage with other objects. …
- 7) Never use a damaged wrench.
Always pull, DO NOT PUSH, to apply torque and adjust your stance to prevent a fall. A “cheater bar” should NEVER be used on a torque wrench to apply excess leverage. Do not use with sockets or fasteners showing wear or cracks. … Make sure direction lever is fully engaged.
In short, having the offset angle allows you to use the wrench in confined spaces as well as on flat surfaces. … However, offsetting it at a 15 degree angle reduces that swing to 30 degrees which makes your work faster and easier.
- Measuring tools.
- Tool belts.
Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools.
Diagonal cutting pliers are used for cutting wire and small pins in areas that cannot be reached by larger cutting tools. Because the cutting edges are diagonally offset about 15 degrees, these can cut objects flush with a surface.
The ICON™ flush cut pliers provide clean cuts to eliminate sharp edges on zip ties, cable or wire bundles.
Diagonal pliers have a pair of jaws, a fulcrum point, and a pair of handles that are often dipped in colored plastic which serves as an insulator. … Diagonal pliers are specially designed pliers used for cutting wire. The jaws are sharp and beveled to cut wire closely and effectively.
The torque wrench’s drive size describes the bits you can use to tighten nuts and other fasteners. The standard sizes include 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch, though you won’t be working with anything above a 1/2-inch drive for most applications.
