Push-On External Retaining Rings
No groove required—press these rings onto the end of a shaft. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip. Styles A, B, and C have teeth that dig into the shaft material, so expect minor scratching. Use a push nut installation tool (sold separately) to install rings, or install them manually.
1050 spring steel and 1060-1090 spring steel rings are an economical choice with good strength. A black finish is the result of a heat treatment to darken them—making them ideal for blending into dark backgrounds. However, these rings will rust if exposed to moisture.

Wire-Lock Clevis Pins
The wire retainer snaps closed to secure the pin for a one-piece alternative to a clevis and cotter pin combination. Also known as PTO pins.
Pins that meet SAE J429 comply with specifications and testing requirements for material quality. They have a coating that protects them from rusting due to salt spray.
