1. Select an appropriate head style.
Ejecting assemblies improve fastener action by springing an unlocked stud clear of the receptacle and holding it in position for straight re-entry. An ejected stud also signals an unlocked fastener.
2. Select a stud retainer:
4. Select a receptacle type:
All receptacles meet the performance specifications, but the riveted and snap-in high-performance rear load offer smoother operation and more even locking torque across their material grip range.
5. Now determine the Panel, Gap, and Support thicknesses.
Now determine the thickness of material in which the stud is retained and to which the receptacle is attached. Then determine the total gap between the level of stud head contact with material and the level of receptacle contact, in the closed position, include any air gaps and any part of the stud retainer thickness not buried in material already measured. Refer to the examples on each receptacle page, which will guide you to the length selection table.
