What is a lug?

A lug is a type of fastener typically used to secure two or more objects together. Lugs are often made of metal and feature a threaded hole that allows them to be attached to a bolt or screw. They are commonly used in engineering and mechanics for securing components such as wheels, gears, and machinery parts.

Lugs come in various shapes and sizes, including round, square, and rectangular. They can also have different designs, such as countersunk lugs that sit flush with the surface they are attached to. Lugs are often used in conjunction with washers and nuts to provide a secure connection.

In addition to their use in mechanical applications, lugs are also commonly used in electrical installations to connect wires and cables. In this context, lugs are crimped or soldered onto the ends of wires to create a secure electrical connection.

Overall, lugs are versatile fasteners that are used in a wide range of applications across various industries.
