What Are Headless Clevis Pins (Plain and with Cotter Pin Holes) Used For?

Typical applications, the industries that specify headless clevis pins (plain and with cotter pin holes), and how to choose the right size, material and finish for the joint.

Headless Clevis Pins (Plain and with Cotter Pin Holes) are used for a headless clevis pin retained at both ends, plain or with cotter pin holes. They are manufactured to ISO 2340, and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

What Are Headless Clevis Pins (Plain and with Cotter Pin Holes) Used For? application image

Headless Clevis Pins (Plain and with Cotter Pin Holes) are used primarily for a headless clevis pin retained at both ends, plain or with cotter pin holes. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to ISO 2340. Stocked across roughly 3 mm to 100 mm, they cover general to heavy-duty work.

Typical Applications for Headless Clevis Pins (Plain and with Cotter Pin Holes)

The most common settings where these are specified:

  • Hydraulic cylinders: rod-end connections.
  • Linkages: pivot pins retained on both sides.
  • Agricultural equipment: hitch and linkage pins.
  • Conveyors: roller and chain pins.

How to Specify Headless Clevis Pins (Plain and with Cotter Pin Holes) 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 3 mm–100 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 2340. 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 Headless Clevis Pins (Plain and with Cotter Pin Holes)

  • 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 Headless Clevis Pins (Plain and with Cotter Pin Holes) Are Not the Right Choice

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

Need a headless clevis pins (plain and with cotter pin holes) outside the standard range?

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.

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.
