38ASSA-01E 10-32 Aluminum Star Captive Screw Knob Assembly - With Captive Retainer Collet

Knob: 6061 Polished - Stud: G-5 - Sleeve: 12L14 black oxide

These captive screw knob assemblies stay with fixture, eliminating lost fastening hardware and allowing for faster change overs and set up. They also add a high quality look and feel to the finished part. These captive fasteners consist of a spring loaded screw knob assembly and collet. These assemblies instantly install in a single hole, or a slotted hole, by inserting the collet through the fixture and securing with the supplied bronze bearing and retainer. When unfastened, the knob is held away from the fixture by spring tension and the screw is fully withdrawn into the collet. This provides a flush surface on the back side of the fixture, which is ideal for sliding surfaces. When fastened, the knob is pulled down over the collet for tight secure clamping. Instructions included.
