## Applications & Industries

The sectors that buy Spiral Retaining Rings, and the duty each one buys them for. Stocked from 10 to 50 (shaft / bore diameter).

### Industries that specify Spiral Retaining Rings

- **Hydraulics & pneumatics:** Holding pistons, glands and seals in bores.
- **Automotive:** Shaft retention throughout the driveline and in accessories.
- **Appliances & mechanisms:** Light axial retention on plain shafts.
- **Gearboxes & drivetrain:** Retaining bearings, gears and pulleys against axial movement.

### Typical applications

- holding a component on a shaft without a shoulder
- axial retention in a machined groove

### Service conditions to specify against

- **Marine and coastal:** Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.

Spiral Retaining Rings conform to Trade series (spiral wound retaining ring). As retaining rings, they are specified by the dimensions in the table below; this page also covers materials, finishes and typical uses.

## What Are Spiral Retaining Rings?

Spiral Retaining Rings are retaining rings defined by Trade series (spiral wound retaining ring). They are selected by shaft / bore diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

## Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.

## Specification Guides

Each size, material and standard of Spiral Retaining Rings has its own reference page with the figures for that one configuration.

## Goes With

Hardware commonly specified alongside Spiral Retaining Rings.

## Pricing

Spiral Retaining Rings are supplied to order. Pricing starts from approximately US$0.11 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

Custom manufacturing · Made to drawing

## Need a spiral retaining rings outside the standard range?

Groove dimensions, thickness, material temper and finish decide the part; the ring is made to the groove, so the groove drawing is what is actually needed. Made by stamping.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Inside the plant

## Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift.
2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g.
3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1.
4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227.
