What is the end of a wrench called?
WRENCH TYPE: Hex-Key Wrench After inserting one end of the hex-key wrench into a hex-head nut, the other end of the wrench is used as a handle to turn the nut. “Cheater bars,” or small tubes that slip over the end of the wrench handle, can create a longer handle and provide increased leverage when the nuts are stuck.
What is an offset wrench?
Offset wrenches are just normal normal box-end wrenches with a bend on each end that helps them reach deeply countersunk nuts or bolts that you can’t get at with sockets or standard wrenches. The kit shown here offers two sizes on each wrench and they’re available in standard or metric sizes.
What is an open ended wrench?
: a wrench with jaws having a fixed width of opening at one or both ends of the handle.
What is the proper way to use a wrench?
The proper way to hold a wrench is by its handle. Turn the nut until the jaws match the job. Place the hook jaw (movable jaw) so that it will point towards the direction you want the job to rotate.
Should you push or pull a wrench?
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.
What can you do with a wrench?
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. There are basically two major kinds of wrenches: Pipe wrenches used in plumbing for gripping round (cylindrical) things.
Can you use pliers instead of a wrench?
Although pliers can be used to tighten and loosen nuts, this is a task better suited to the wrench. Pliers tend to damage the surfaces of fasteners and are usually more difficult to use than a properly-sized wrench.
What is a flare nut wrench used for?
While a flare nut wrench is an open-ended wrench that is designed for fastening or loosening hexagonal nuts and fittings. Regular wrenches are mostly used for turning rotatory fasteners such as nuts and bolts or to keep them tight. A flare nut wrench, conversely, is typically used for machine work or for plumbing.
What’s the difference between a spanner and a wrench?
The term wrench is generally used for tools that turn non-fastening devices (e.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. In American English, spanner refers to a specialized wrench with a series of pins or tabs around the circumference.
What does a spanner wrench look like?
There are many types of spanner wrenches, each with a distinctly shaped hook. In addition, some spanners are multi-tools with double-sided hooks. The most common type of spanner wrench is the C spanner. Its head is open in the shape of the letter C, and its jaws are meant to correspond to the similarly sized nut.
What’s the difference between a socket wrench and a ratchet?
A socket wrench is a type of wrench (spanner in British English) that inserts into a socket to turn a fastener, typically in the form of a nut or bolt. The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.
What properties does a spanner need to have in order to be used to tighten bolts?
What properties does a spanner need to have in order to be used to tighten bolts? The spanner must be hard and strong. How do the properties of metal help the functioning of a spanner? The metal is strong and hard and the spanner needs to be strong and hard.
Which type of socket handle provides maximum leverage to loosen a bolt?
The hinged handle is used when additional leverage or torque is needed to loosen nuts or bolts.
Do not use the hex driver which is too big for the bolt you are using?
Use a hex driver, shown in Figure 2-10, to loosen and tighten bolts that have a hexagonal (six-sided) head. Hex bolts should not be over-tightened because the threads of the bolts can be stripped. Do not use a hex driver that is too large for the bolt that you are using.
What factors determine which wrench to use?
Some of the factors to consider in designing or selecting a safe series of wrenches and fasteners include: maximum tightening torque, maximum removal torque, minimum torsional strength, and torques from wrench specifications.
What is another name for a hex wrench?
A hex key, also known as an Allen key or Allen wrench, is a small handheld tool that’s used for for driving bolts and screws with a hexagonal socket. They are available in many different sizes, though they all have the same hexagonal-shaped tip.

What should you not do with a torque wrench?
Users should never put a pipe or any other kind of extension onto a torque wrench handle as doing so can seriously damage the tool and make it inaccurate, never mind the potential safety hazard.
Can you over tighten with a torque wrench?
A torque wrench prevents but do not avoid over tightening! The good practice here is to start over : Loosen the bolt first, tighten with an adapted tool and finish with the torque wrench to reach the correct and safe torque.
Should you double click a torque wrench?
Double checking your torque is never a bad thing. By double clicking, you are allowing the fastener to rest for a second, then you are back at it to get the proper amount of torque there.
How should a torque wrench be left after use?
Storage: All torque instruments should be stored in their original case. Avoid any torque wrench storage locations that are subject to high or low temperatures and high humidity. “Clicker” style torque wrenches should always be turned down and stored at the torque wrenches lowest possible setting.
Why does my torque wrench not click?
Test it with a bolt thats already tight, but set the wrench lower than the bolt should be tightened to to make sure it still clicks. If it doesn’t click before the bolt turns, it likely needs to be opened up to re-position the bearing.
How often should a torque wrench be calibrated?
every 5000 cycles
What setting should my torque wrench be on?
If you expect to store a torque wrench for more than a few weeks, always wind it down to the lowest scale setting (never to zero). Storing a fully loaded torque wrench can result in a set in the spring, weakening the spring over time.
How much does it cost to calibrate a torque wrench?

Where can I get my torque wrench calibrated?
The best place to get a torque wrench calibrated is at a torque calibration laboratory that is capable of handling any type of torque tool, even torque multipliers, with up to 35,000 pound-feet (lb. ft) capacities and torque transducers that can measure up to 20,000 lb.
Can you calibrate your own torque wrench?
However, torque wrenches need to be calibrated regularly to make sure they’re giving accurate readings. While it may be best to take your torque wrench to a professional for calibrations, you can do a pretty good job of keeping your torque wrench accurate by calibrating it at home.
Do digital torque wrenches need calibrated?
As a general rule of thumb all torque wrenches should be re-calibrated at least once per year or every 5000 cycles.
How long does a torque wrench last?
After 5000 cycles or up to one year of use, whichever comes first, have your torque wrench inspected and recalibrated by the manufacturer or reputable calibration service. With proper care, a high-quality torque wrench should provide accurate measurements for many years.
