# What Are Clevis Pins (ISO 2341 / DIN 1444) Used For?

Pins · ISO 2341 · Application guide

Typical applications, the industries that specify clevis pins (iso 2341 / din 1444), and how to choose the right size, material and finish for the joint.

Clevis Pins (ISO 2341 / DIN 1444) are used for pivot and linkage joints that carry shear on a plain shank and are retained by a split pin or a clip. They are manufactured to ISO 2341, and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

- **Primary duty:** Pivot and linkage joints that carry shear on a plain shank and are retained by a split pin or a clip
- **Governing standard:** ISO 2341
- **Nominal diameter range:** 4 mm to 16 mm
- **Category:** Pins

Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation.

Clevis Pins (ISO 2341 / DIN 1444) are selected when an assembly calls for pivot and linkage joints that carry shear on a plain shank and are retained by a split pin or a clip. This application guide to the ISO 2341 type covers concrete end-uses, the specification checklist, correct installation, and where an alternative fastener performs better. Stocked across roughly 4 mm to 16 mm, they cover general to heavy-duty work.

## Typical Applications for Clevis Pins (ISO 2341 / DIN 1444)

The most common settings where these are specified:

- **Jigs & fixtures:** precise location of tooling plates and locating features.
- **Linkages & hinges:** pivot points carrying light shear.
- **Machine alignment:** dowelling mating housings so they reassemble in the same position.
- **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment.
- **Maintenance & repair (MRO):** a stocked size for servicing existing plant where the original fastener spec must be matched.

## How to Specify Clevis Pins (ISO 2341 / DIN 1444) for Your Application

- **Size:** Select on nominal diameter, then on the hole tolerance and fit class — the fit, not the diameter alone, determines whether the part locates or slips. This product spans 4 mm–16 mm; check the full table below for the exact dimensions of each size.
- **Material:** Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- **Environment:** For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- **Standard:** This product is supplied to ISO 2341. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Installation & Assembly Practice

- Ream the hole to the specified fit class; a dowel pressed into a drilled-only hole will not locate accurately.
- Press pins in with steady force rather than hammer blows where possible, and chamfer the hole entry.

## Common Selection Mistakes with Clevis Pins (ISO 2341 / DIN 1444)

- Using a dowel pin as a load-carrying shear bolt — dowels locate, they are not sized for sustained shear.
- Ignoring the fit class: a locational fit and an interference fit need different hole tolerances.

## Where Clevis Pins (ISO 2341 / DIN 1444) Are Not the Right Choice

Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that.

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

### What material should Clevis Pins (ISO 2341 / DIN 1444) be for outdoor use?
