SUS304, SUS316 Stainless Steel Socket Cap Sems Screws With External/internal Tooth Lockwashers and Flat Washer
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.
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
