1. Description:
SEMS Screws
Washers are often used in combination with screws to improve the structural integrity of an assembly. Typically, they are separate components. However pre-assembled screws and washers – the SEMS screw, have simplified and improved efficiencies in many manufacturing processes.
What is a SEMS Screw?
A SEMS Screw is a generic term used to describe a screw pre-assembled with a free-spinning lock washer. It is a permanent assembly with the washer held in place by the major diameter of the screw thread being larger than the hole of the washer. The SEMS screw is simple, easy to use and available in many different styles making it well suited for many applications.
