About Nuts, Materials, and Finishes

A barrel with multiple threads ensures secure thread engagement. Also known as U-style clip-on nuts, these nuts firmly clip onto the edge of panels and stay secure.

Zinc-plated steel clip-on nuts are corrosion resistant in wet envrionments.

Black-phosphate steel clip-on nuts are mildly corrosion resistant in dry environments.

Metric Clip-On Nuts for Flanged Edges

Slide these nuts on the edge of a panel and position them by hand. Also known as G-style clip-on nuts, they have threads that float inside the retainer so you can install a bolt at a slight angle to align off-center parts. A zinc plating provides corrosion resistance in wet environments.

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. 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.

15-7 PH stainless steel rings have high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.

Side-Mount External Retaining Rings

Also known as E-style rings, these rings have three prongs that make contact with the shaft and provide a wider shoulder than other external rings for a larger retaining surface. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. Ring OD is measured with the ring uninstalled.

1060-1090 spring steel and spring steel rings are an economical choice with good strength. A black-phosphate finish is mildly corrosion resistant in dry environments. DIN 1.4122 stainless steel rings withstand wear caused by abrasion, similar to 400 series stainless steel. Rings are passivated for added protection against corrosion.

Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Side-Mount External Retaining Ring Assortments

E-Style Side Mount

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface. All are magnetic.

Black-phosphate steel retaining rings resist corrosion in dry environments.
