Push On Retaining Ring Zinc Plated 3/8 * 3/4 OD.

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.

1050 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, while a zinc-plated finish is corrosion resistant in wet environments.
