Metal Fasteners: What to Know

There are two kinds of metal fasteners. The first one produces a permanent bond while the other type requires either a releasable or a sliding bond. A screw, rivet, bond, retaining ring, and clamp are examples of permanent metal fastener. Non-permanent fasteners include quick-release couples and clamps meant for removal at a certain time and pins.

Every metal fastener is made strong so it can bear significant loads. Usually, manufacturers make their products using a powder metallurgic or casting technique.  A lot of kinds of metal fasteners have iron, though titanium is increasingly being used in applications where strength should be balanced against light weight. In the majority of applications that require permanent bonding, metal fasteners can be replaced through some kind of welding or soldering.
