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

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.

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

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
    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
    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
    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
    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?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

Are Clevis Pins (ISO 2341 / DIN 1444) made to a recognized standard?

Yes — they are manufactured to ISO 2341, so dimensions are interchangeable between suppliers when you quote the standard on your order.

What are Clevis Pins (ISO 2341 / DIN 1444) 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 supplied to ISO 2341.

Which industries use Clevis Pins (ISO 2341 / DIN 1444)?

They are commonly specified in machine alignment, general machine building and maintenance & repair (mro), among other sectors.
