Machine screws are fasteners designed to hold objects together, typically made of metal. They have a uniform diameter and a threaded shaft, allowing them to be easily inserted into pre-drilled holes. Machine screws are commonly used in machinery, electronics, and construction due to their strength and versatility. These screws come in various sizes and types, including flat head, pan head, and hex head, each serving different purposes. They are often paired with nuts or used with tapped holes to create a secure connection. Machine screws are essential components in many applications, providing reliable fastening solutions.
