# A4 (316) Stainless Steel Gas Drive Pins

Nails · Trade series (collated gas drive pins)

Mechanical properties, corrosion behaviour and the full dimensional range for this grade.

A4 Stainless Steel Gas Drive Pins are supplied to ISO 3506 group A4 (316 / 1.4401), commonly supplied A4-80. Corrosion behaviour is superior, including marine and chloride environments, the material is largely non-magnetic, and the usable service range is approx. -200 °C to +400 °C, subject to the property class and the joint. In practice this grade is specified for marine, coastal and chemical applications.

- **Grade:** ISO 3506 group A4 (316 / 1.4401), commonly supplied A4-80
- **Corrosion resistance:** Superior, including marine and chloride environments
- **Magnetic response:** Largely non-magnetic
- **Service temperature:** approx. -200 °C to +400 °C, subject to the property class and the joint

Property values are typical for the grade. Certified mechanical test data is available on request for production orders.

## Need this nail in a grade that is not listed?

A4 Stainless Steel is one of the grades the catalog describes. A non-standard nail is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling.

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

## Applications & Industries

The sectors that buy Gas Drive Pins, and the duty each one buys them for.

### Industries that specify Gas Drive Pins

- **Building services:** Fast fixing of clips and hangers to structure.
- **Formwork:** Collated strips keep the tool loaded on repetitive work.
- **Fit-out contracting:** No drilling and no plugs on high-volume fixing.
- **Drywall track fixing:** Gas tools set pins into concrete and steel at speed.
- **Fencing & landscaping:** Outdoor timber fixing.
- **Construction & framing:** Timber framing, sheathing and battens.

### Typical applications

- selecting pin length for the substrate and the fixture
- choosing the washer variant where the fixture needs bearing area
- checking the substrate rating before firing
- loading the collated strip into the matching gas tool
- high-volume assembly with a nail gun
- fast permanent fixing in timber

### Service conditions to specify against

- **Exterior structural:** Hot-dip galvanised options for external steelwork; allow for the thicker coating in the mating thread.

### Where to use something else

- Do not fire a drive pin into a substrate the tool is not rated for; the pin can ricochet or pass straight through.

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.

## Frequently Asked Questions

### Can A4 Stainless Steel replace plated alloy steel structurally?

Only at the standard strength classes — A2-70 / A4-80 are roughly equivalent to class 7 steel; A4-100 reaches class 8.8. For class 10.9 or 12.9 strength, plated alloy steel is required.

### Are A4 Stainless Steel Gas Drive Pins magnetic?

A4 Stainless Steel Gas Drive Pins are largely non-magnetic.

### What corrosion resistance do A4 Stainless Steel Gas Drive Pins offer?

A4 Stainless Steel Gas Drive Pins provide superior, including marine and chloride environments with a service range of approx. -200 °C to +400 °C, subject to the property class and the joint.

### Should I choose A4 Stainless Steel or A2 (304) for Gas Drive Pins?

For Gas Drive Pins, A4 Stainless Steel suits general indoor and outdoor use; A2 (304) is preferred for marine, coastal and chemical environments. Choose by corrosion exposure first.
