Hex Head Cylinder Head M4 M6 Stainless Steel Sems Screws By Internal Tooth Washer

1. Descriptions:

 

     SEMS Screws feature a one-piece screw and washer assembly, which results in a quicker and easier production line over a two-piece screw and washer assembly.

 

      Many fasteners are available as assemblies with captivated washers, collars, specialized stampings, or other components. Captured washers improve productivity; eliminate lost, dropped, or forgotten washers; and simplify purchasing and inventory control, as it combines two part numbers into one.Engineered assemblies, which combine metal, plastic, and other components into one subassembly, are also available.

 

       To improve the integrity and strength of assemblies, washers are often used along with screws. It was a great leap forward when screws and washers became pre-assembled into the SEMS screw. This screw includes a free-spinning washer that is locked into place because the screw thread (created after the washer is put on) is larger than the hole of the washer. SEMS are low cost, easy to use and are available from our company in many different sizes, styles, head types, drives,materials and other choices,depending upon your application needs.

 

        The Double Washer SEMS is a fastener with two free-spinning washers. At SEMS and SPECIALS, we offer them in standard and metric sizes.

3. FAQ:

 

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.

 

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

 

4. Advantage:

  • One-piece screw and washer assembly.
  • Provides a larger bearing surface area than a one-piece cold formed part.
  • Provide a screw and washer assembly with dissimilar material.
  • Provides a more consistent torque/tension relationship.
  • Distributes the load over a large bearing surface, reducing potential joint yielding.
  • 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
