0-80 Set Screws

Set Screws Explained

0-80 Set screws (among other sizes)

are a type of fastener designed to hold two or more objects together. They consist of a threaded shaft and a head that can be tightened using a screwdriver or wrench. Unlike other screws, set screws do not have a pointed end and are typically used to secure objects in place rather than joining them together.

0-80 Set screws (and other sized set screws) are commonly used for applications that require a strong and reliable connection, such as machinery, electrical equipment, and furniture. They can also be used for positioning and alignment purposes, as well as securing parts that may be subject to vibration or movement.

There are different types of set screws available, including cup-point, cone-point, and flat-point set screws. The type of set screw used will depend on the specific application and the type of material being fastened.
