A workshop fastener is a device used to secure two or more objects together. The two most common types of workshop fasteners are clamps and tnuts. Clamps are typically made of metal and have two parts that can be tightened together to hold an object in place. Tnuts are threaded nuts that are inserted into a hole and secured with a bolt or screw. Both clamps and tnuts are essential components of any workshop and are used to secure materials for projects.
