SUS304 SUS316 Socket Cap Sems Screw External / Internal Tooth Lockwashers And Flat Washer

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.

Advantages of the SEMS Screw:

• Low cost and widely available
• Increases productivity by eliminating hand assembly of individual components
• Permanent assembly assures that the washer is not dropped, lost or forgotten
• Ease of use with hand drivers and in automated production programs
• Available in most screw and washer combinations

Key Considerations When Choosing SEMS Screws:

• Select the correct configuration for the specific task at hand
• Good design ensures savings in the long run
• Proper finishes perform optimally and are aesthetically pleasing
• Ease of use, particularly in difficult spaces
