Fasteners
What are fasteners?
Fasteners are mechanical devices used to join or affix two or more objects together, providing structural integrity and load-bearing capability in various assemblies. They are essential in virtually every industry, from construction and automotive to electronics and aerospace, offering quick, reliable, and often removable connections.
Fasteners come in multiple materials such as carbon steel, alloy steel, brass, copper, aluminum, and stainless steel, and are designed in numerous forms including nuts, bolts, screws, washers, studs, and anchors to suit diverse mechanical requirements.
