Push-On Retaining Caps
Use these caps to hold components in place and protect shaft ends. Install these caps with a hammer or push them into place by hand.
Corrosion-resistant-coated finish is more corrosion resistant in wet environments than zinc plated finish. Also known as black luster.
Nickel-plated finish has excellent corrosion resistance and a decorative appearance.
Zinc-plated finish is corrosion resistant in wet environments.

Flanged Push-On External Retaining Rings
The wide flange provides better load distribution than standard external push rings and can be used to cover oversized holes. Also known as thread cutting nuts. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip.

Retaining Caps for Quick-Release Pins
Press a retaining cap onto the end of a pin to hold it in a hole that's oversized or out of round. They're made of 18-8 stainless steel for a balance of strength and corrosion resistance.
Caps with screw included provide a convenient attachment point for a lanyard (sold separately).
Caps that are passivated offer added protection against corrosion and oxidation.
