Ball detent depresses and springs up for "quick
release" applications. Used as a convenient way to adjust or remove
accessories on equipment. A stainless steel ball is supported by polyeurathane.
This design is low cost and superior in its resistance to foreign material
contamination which would shorten ball life.
Standard sizes are made from 12L14 carbon steel zinc plated.
Rigid quality control procedures ensure a consistent fastener you can count
on.
