ASME B18.13 Machine Screw and Washer Assemblies - Sems by Material, Finish and Size

SEMS® Machine Screws are machine screws with pre-assembled captive washers, designed to speed total assembly time in a manufacturing process.

Search thousands of US/Imperial fasteners by ASME specification, including ASME b18.13 SEMS Machine Screws, in the FCH Sourcing Network database of first-run, surplus, odd lot, slow-moving and hard to find fasteners.

SEMS® Machine Screws come pre-assembled with a free rotating lock washer that is firmly kept in place by the screw's thread's main diameter. This removes the need to manually attach washers to the screw, saving you time, money, and the risk of washers being lost or dropped in the production line. SEMS screws combine two different parts into a single, low-cost fastener that is pre-assembled. They combine two separate parts into a single, low-cost pre-assembled fastener. SEMS® Machine Screws are similar to regular machine screws in that they require a pre-drilled hole.
Common applications of SEMS Machine Screws are:

  • • Electronics
  • • Medical
  • • Automotive
