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.
Advantages of the SEMS Screw:
1. Low cost and widely available
2. Increases productivity by eliminating hand assembly of individual components
3. Permanent assembly assures that the washer is not dropped, lost or forgotten
4. Ease of use with hand drivers and in automated production programs
5级Available in most screw and washer combinations
Key Considerations When Choosing SEMS Screws:
1. Select the correct configuration for the specific task at hand
2. Good design ensures savings in the long run
3. Proper finishes perform optimally and are aesthetically pleasing
