An impact socket is used to loosen or tighten fasteners with percussion instruments. They are made of soft steel and have a black oxide or plastic coating instead of chrome finish. Impact sockets are safer to use as they are less likely to break and cause injury. They can be used with electric, pneumatic, or hand tools.
An impact socket is a tool that can be used to loosen or tighten a fastener. The purpose of impact sockets is to resist the force applied by percussion instruments, which can cause standard sockets to break. To achieve this, an impact socket will typically be made from a relatively soft steel and have a black oxide or plastic coating instead of a chrome finish. This may allow impact sockets to be used in conjunction with hand ratchets or percussion instruments, although many people own sets of both and use each type only for its intended purpose.
Sockets are interchangeable tools that can allow a single wrench, impact wrench, or breaker bar to work with a large number of fastener sizes. Socket wrenches with a single female socket have been around for hundreds of years, but the first tool that allowed multiple socket wrenches to be connected to a single drive was invented in 1863. The impact socket arrived later, with the introduction of power tools. and tyres.
There are two main differences between standard sockets and impact sockets, which are designed to offer greater safety during use. The first is the material from which the sockets are constructed. Most standard sockets are made of steel that is very strong and resistant to deformation during use. This type of steel is also very brittle, so when it breaks it tends to shatter. To avoid potential injury from flying shrapnel, impact sockets tend to be made of softer steel that will crack or warp rather than break.
The other major difference between a standard socket and an impact socket is the finish. To reduce the risk of rust and create a visually attractive finish, many sockets are chrome plated. When subjected to impact forces, this chromium can chip and fly off. These bits of plating material are less likely to cause injury than broken grip pieces, but the rust may settle after the plating is gone. Impact sockets receive the same type of rust protection from coatings of substances such as black oxide or plastic, which are less likely to chip and chip than chromium.
Many tools are designed specifically for use with impact sockets. Both electric and pneumatic versions of impact wrenches and air guns can provide enough torque to use an impact socket to avoid potential injury. Impact sockets can also be used with hand tools, such as ratchets and wrecking bars. If there is any concern that the level of torque applied may break the socket, it may be safer to use an impact socket than to use a standard one.
