What is a wrench made out of?

Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning.

What type of steel is used to make wrenches?

Chromium vanadium steel is an alloy tool steel with chromium (Cr) and vanadium (V) alloy elements. It has better strength and toughness than carbon steel, so it is a great material for high quality tools. Commonly used for wrenches, screwdrivers, manual sleeves generally use 50BV30 chrome vanadium steel.

What is the structure of a wrench?

Basically, a wrench consists of a stout lever with a notch at one or both ends for gripping the bolt or nut in such a way that it can be twisted by a pull on the wrench at right angles to the axes of the lever and the bolt or nut.

What metal are Craftsman wrenches made of?

During the 1930s Sears used the "Vanadium" mark as a sub-brand on many of its Craftsman tools, including open-end wrenches, box wrenches, and pliers. This use of Vanadium as a sub-brand was undoubtedly intended to draw attention to the alloy steel used for the tools.

What are the parts of a wrench called?

A combination wrench is essentially three parts: an open end, a beam and a boxed end. Despite only having three parts, there are a few different ways to shape them. On the open end side, it's pretty simple -- you can have standard jaws or a modified open end.

How strong is vanadium steel?

The minimum tensile strength of chrome vanadium is particularly high compared to other alloys and is normally between 190 and 300, depending on grade and nominal chemical composition.

Are wrenches tempered?

A good quality hex wrench is characterized by toughness, and that typically means it's been heat treated to harden and tempered. Keep in mind this is what makes metal strong without being brittle, so your Allen wrench will offer a superior experience in high torque applications. Rust resistant coating.

What type of tools are wrenches?

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.

Who makes the strongest wrench?

Best Overall: GEARWRENCH 20-Piece Ratcheting Wrench Set

With a whopping total of 20 sizes, 10 metric and 10 SAE, these double-sided wrenches—which boast both open and box ends—have got you covered.

Why is a wrench called a spanner?

First used in 1790. 'Spanner' came into use in the 1630s, referring to the tool for winding the spring of a wheel-lock firearm. From German Spanner (n.), from spannen (v.) ("to join, fasten, extend, connect"), from Proto-Germanic *spannan, from PIE root *(s)pen- ("to draw, stretch, spin").

What does a socket wrench do?

A socket wrench or ratchet allows you to turn nuts and bolts with more ease than using a regular wrench. The ratcheting feature allows you to keep the wrench on the bolt eliminating the need to refit the wrench every time you need to make a turn.

How is a spanner made?

Most types of spanner are made using the drop forging process. Steel rods are cut into short lengths, called billets, and each one is passed through an induction heating coil which uses electromagnetism to heat the metal to about 1000 degrees Celsius. ... The upper die drops onto the billet, forcing it into shape.

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.

How is Chrome Vanadium made?

Chrome vanadium, sometimes called Cr-V, is a unique type of steel created by combining chromium and vanadium alloy elements. It's usually used for steel hand tools, large-diameter spring wires, and other high-stress applications.

What is chromium alloy steel?

Chromium-molybdenum alloy steel (or chrome moly), is an alloy used for high pressure and temperature use. It is used in oil and gas, energy, construction and the automotive industries because of its corrosion resistance and high-temperature and tensile strength.
