# A2 (304) Stainless Steel Ball-Lock Pins (T-Handle)

Pins · Trade series (ball-lock quick pin)

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

A2 Stainless Steel Ball-Lock Pins (T-Handle) are supplied to ISO 3506 group A2 (304 / 1.4301), commonly supplied A2-70. Corrosion behaviour is good general corrosion resistance, 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 the most common stainless group for indoor and general outdoor fasteners.

- **Grade:** ISO 3506 group A2 (304 / 1.4301), commonly supplied A2-70
- **Corrosion resistance:** Good general corrosion resistance
- **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.

A2 Stainless Steel (ISO 3506 group A2 (304 / 1.4301), commonly supplied A2-70) is the most common stainless group for indoor and general outdoor fasteners. Specified on ball-lock pins (t-handle) it determines the corrosion behaviour (good general corrosion resistance) and the service temperature range (approx. -200 °C to +400 °C, subject to the property class and the joint); the dimensions are ours rather than a standard's, and are listed in full below.

## Why Choose A2 Stainless Steel for Ball-Lock Pins (T-Handle)

The most common stainless group for indoor and general outdoor fasteners. For ball-lock pins (t-handle), this matters when good general corrosion resistance is the primary requirement.

## Mechanical & Physical Properties

| Grade designation | ISO 3506 group A2 (304 / 1.4301), commonly supplied A2-70 |
| --- | --- |
| Magnetic response | Largely non-magnetic |
| Service temperature | approx. -200 °C to +400 °C, subject to the property class and the joint |
| Corrosion characteristic | Good general corrosion resistance |

## Corrosion Behavior in Service

A2 (304) gives excellent atmospheric and most-water corrosion resistance and is the most common stainless for Ball-Lock Pins (T-Handle) in indoor and general outdoor service. In chloride-bearing environments (marine air, road salt, swimming pools) consider stepping up to A4 (316).

## Galvanic & Galling Considerations

For stainless ball-lock pins (t-handle) the compatibility question is galvanic rather than galling: joined to aluminum or galvanized steel in wet service, stainless drives corrosion of the less-noble metal. Isolate with a coating, sleeve or non-conductive washer where the joint sees moisture. Note also that stainless is softer than hardened carbon steel, so where the part carries a wear or shear duty, check the load against the grade before substituting.

## Using Stainless Fasteners in Aluminum

Stainless steel is more noble than aluminum, so with an electrolyte present — rain, condensation, salt spray — the aluminum becomes the anode and corrodes at the joint. Area ratio decides how bad it gets: a small stainless fastener in a large aluminum section is normally acceptable, a large stainless fastener in thin aluminum is not. Where the joint gets wet, isolate the metals with a coated or nylon washer and a sealant, or specify an aluminum or coated fastener instead.

Custom manufacturing · Made to drawing

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

A2 Stainless Steel is one of the grades the catalog describes. Tolerance class is what a special pin usually turns on — a locating pin and a retaining pin want very different fits in the same nominal size. Made by cold heading or turning.

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

## Applications & Industries

The sectors that buy Ball-Lock Pins, and the duty each one buys them for. Stocked from 5 to 16 (nominal diameter).

### Industries that specify Ball-Lock Pins

- **Jigs, tooling & workholding:** Connections made and broken many times a day.
- **Sports & access equipment:** Folding frames, towers and staging.
- **Aerospace ground equipment:** Quick connections with a positive lock.
- **Agricultural machinery:** Hitching implements, guards and adjustable linkages.
- **Machine building:** Hinges, pivots and linkages carrying light to moderate shear.
- **Agricultural & plant:** Implement connections made and broken in the field.

### Typical applications

- connections made and released by hand in seconds
- ball-lock pins for a positive, load-rated lock
- hitch and linch pins where a wire clip is enough
- locating two parts to a repeatable position
- pivot and hinge joints loaded in shear
- quick connections made and broken by hand

### 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.
- **Vibration:** Specified where cyclic load would loosen a plain nut or screw — rotating plant, rail, mobile equipment and anything that is not re-torqued in service.
- **Hole preparation:** The hole is half the specification: a ground dowel needs a reamed H7 hole, a grooved or spring pin will hold in a drilled one.

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

### Should I choose A2 Stainless Steel or A4 (316) for Ball-Lock Pins (T-Handle)?

For Ball-Lock Pins (T-Handle), A2 Stainless Steel suits general indoor and outdoor use; A4 (316) is preferred for marine, coastal and chemical environments. Choose by corrosion exposure first.

### Can A2 Stainless Steel Ball-Lock Pins (T-Handle) gall during installation?

Yes — stainless on stainless is prone to thread galling under load, especially at smaller sizes. Use an anti-galling lubricant or wax thread compound, and slow the tightening rate where possible.

### Is A2 Stainless Steel food-grade?

A2 (304) is widely accepted for food contact in non-chloride environments; A4 (316) is preferred where chlorides are present.

### Can A2 Stainless Steel Ball-Lock Pins (T-Handle) be used with aluminum?
