Push-On External Retaining Rings
A
B
C
D
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. Black-phosphate finish is mildly corrosion resistant in dry environments. In wet environments, a zinc yellow-chromate plated finish has some corrosion resistance, and a zinc chromate plated finish has good corrosion resistance.
18-8 stainless steel rings have good corrosion resistance. A passivated finish adds protection against corrosion.
15-7 PH stainless steel rings have high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.

Rectangular Push-On External Retaining Rings
Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip.

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.

Self-Locking External Retaining Rings
No groove is required for these light duty rings—their thick profile helps them grip the shaft. Open them with retaining ring pliers (sold separately), pass them over the end of a shaft, and release to install. Ring ID is measured with the ring uninstalled.
1060-1090 spring steel has good strength. A black-phosphate finish is mildly corrosion resistant in dry environments.
15-7 PH stainless steel has high strength with good corrosion resistance. These rings are passivated for extra protection against corrosion.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
