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 threaded hole, by inserting the collet
into the fixture and securing tight. Collet has wrench flats for easy
installation. 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spring tension and the screw is fully withdrawn into the collet.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.
