SEMS screws

“Screw & Washer Assemblies” are known as “SEMS” in the fastener industry.

They consist of a screw with an integrally retained washer. The washer is installed during the thread rolling process resulting in the washer being retained above the thread  start. Similar to KEPS nuts many washers types are available, including toothed, conical, conical toothed, flat and specialty washers.

SEMS offer a big efficiency savings for rapid assembly processes and the cost is reasonable compared to purchasing the two components separately.

AMK offers a considerable selection of SEMS screws with machine thread or tapping threads.

Here are some examples of SEMS screws we carry. Most SEMS screws offered by AMK Products are Made in USA.
