Bolts and screws are the most common fasteners on any project. If a bolt or screw is too loose, it will spin freely in a threaded hole as you tighten it. This means that the torque rating is more important than the length of the bolt or screw when determining how tight to make your fastener.
The torque is the force applied to a bolt that is needed to tighten it.
Different Types of Bolts
There are many different types of bolts that can be used for different purposes. Bolts come in a variety of sizes and shapes and are made from a range of materials, such as steel, aluminum, brass, or stainless steel.
The most common types of bolts include hex bolts, square head bolts, sheet metal screws, and machine screws.
Measuring Torque On A Bolt
There are three types of torque specifications for bolts: inch-pounds, foot-pounds, and Newton meters. The torque specification for bolts is measured in inch-pounds. The more torque applied to a bolt, the tighter it will be.
Torque is the measure of twisting or turning force. Turning the bolt means applying torque to it. The unit of torque is kilogram-centimeter or pound-foot. Torque specifications are defined as a ratio of force to distance.
The higher the torque specification, the tighter the bolt is. For example, torque can be measured by using a torque wrench. The torque wrench has a dial and a handle. The dial is used to measure the torque and the handle to apply the torque.
