		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		spring tension and the screw is fully withdrawn into the collet.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.
