co-extruded self retaining screw spacers

CRS Spacers provide precise spacing of electro-mechanical assemblies and

eliminate shakes and rattles associated with movement in high-vibration

PC-board applications, such as large rack-mounted fan cooling trays and

multiple trays found in telecommunications, industrial networks, and

avionics applications.

Designed with Bivar's patent-pending technology, these co-extruded self

retaining screw spacers feature a soft pliable inner lining with a hard

outer shell composed of UL rated 94V-0 PVC material. This unique design

requires only a minimal amount of manual insertion force to cause the

spacer's soft inside material to conform to the threads of the screw. The

cushioning of the encapsulated screw and self-tapping design structure

secures the screw in place, ensuring tight retention.
