Need a clevis pin a stockist can't supply? If it's an odd diameter, an over- or under-size head, a special grip length, an extra split-pin hole or a groove for a circlip, it has to be turned to order — standard ISO 2341 sizes too, from a single piece.
What Is a Clevis Pin?
A clevis pin joins a clevis — a U-shaped fork — to a rod, tang or linkage, forming a pivoting or quick-release connection that carries shear load. Most have a flat head at one end and a cross-drilled hole at the other for a split pin or R-clip to hold them in place; others are headless with a hole each end, or grooved for a circlip. Because the pin is the load-bearing pivot, its diameter, grip (effective) length and hole position are the features that matter — and the reason a non-standard one has to be made rather than bought.
Types We Machine
Headed, with hole (ISO 2341B / DIN 1444B)
Flat head one end, cross-hole for a split pin or R-clip — the standard clevis pin.
Headed, plain (ISO 2341A)
Flat head, no hole — retained by other means or a press fit.
Headless (ISO 2340 / DIN 1443)
No head, a hole at each end for retainers — pivots inside a joint.
Grooved for a circlip
Machined groove for a circlip or E-clip instead of a split pin.
Large / special heads
Over-size heads and washers for bearing on soft or slotted material.
Non-standard & to drawing
Odd diameters, grip lengths, extra holes, stepped or shouldered forms.
Forms & Standards
| Form | Standard | Retained by |
|---|---|---|
| Headed, with hole | ISO 2341 form B, DIN 1444 | Split pin / R-clip |
| Headed, plain | ISO 2341 form A | Press fit / other |
| Headless | ISO 2340, DIN 1443 | Split pin both ends |
| Grooved | To drawing (DIN 1434 style) | Circlip / E-clip |
| Non-standard | To your drawing or sample | As required |
What We Need to Quote
| Detail | What to tell us |
|---|---|
| Diameter | Pin shank Ø (metric or imperial) |
| Grip / length | Effective (grip) length and overall length |
| Head | Standard, over-size, or headless |
| Retention | Split-pin hole (and its position), or groove for a circlip |
| Material & finish | Steel/zinc, A2, A4, brass; hardened if high-wear |
| Clip needed? | Matching split pins or R-clips supplied if wanted |
Materials & Finishes
| Material | Best for |
|---|---|
| Mild / carbon steel (self-colour or zinc) | General linkages and pivots, low cost |
| Alloy steel, hardened | High-wear pivots and heavy shear load |
| Stainless A2 (304) / A4 (316) | Marine, agricultural, outdoor and hygienic use |
| Brass & bronze | Non-magnetic, decorative, corrosion-resistant |
Material certification to EN 10204 3.1 and inspection are available on request under our ISO 9001:2015 system.
Typical Applications
- Linkages, levers and quick-release pivots
- Hydraulic and pneumatic cylinder rod-end and clevis mounts
- Agricultural, trailer and towing equipment — worn pins in the field
- Machinery guards, gates and adjusters
- Restoration and replacement parts where the original pin is no longer sold
Only have the worn pin? Send it — we gauge the diameter, head, grip length and hole position, restore worn features to the original, and turn a matching pin in the right material. No drawing needed; see how we reverse engineer from a sample.
Custom & Non-Standard Clevis Pins — Our Speciality
Stock ranges cover common ISO 2341 sizes in steel and stainless. Everything else is us: odd diameters, special grip lengths, over-size heads, extra or repositioned split-pin holes, grooves for circlips, stepped or shouldered pins, and hardened or exotic materials. Draw it, or send the pin you're copying — with no tooling cost, one piece is a normal order, and we keep the CAD on file for reorders. See also our dowel pins and shoulder bolts & pins.
Frequently Asked Questions
A headed pin that joins a clevis (U-fork) to a rod or linkage, forming a pivoting or quick-release connection carrying shear load. Most have a head one end and a cross-hole for a split pin or R-clip the other; some are headless or grooved for a circlip.
Yes — our core work. Non-standard diameters, over/under-size heads, special grip lengths, extra or repositioned holes, and grooves for circlips, to your drawing or from a sample. One piece, no tooling cost.
Headed (ISO 2341/DIN 1444): head one end, split-pin hole the other. Headless (ISO 2340/DIN 1443): holes both ends. Grooved: a machined groove for a circlip instead of a split pin. We make all three.
Yes. Send the worn or seized original; we gauge the diameter, head, grip length and hole position, restore worn features, and turn a matching pin. No drawing or CAD needed — ideal for linkage, hydraulic and agricultural machinery.
Mild/carbon steel (self-colour or zinc), A2 (304) and A4 (316) stainless, brass and bronze, and hardened alloy steel for high wear. A4 for marine/agricultural; hardened for heavy-duty pivots.
ISO 2341 (headed, forms A plain and B with hole), ISO 2340 (headless), DIN 1444, DIN 1443 and DIN 1434 — or exactly to your drawing for non-standard heads, grips and holes. Certification and inspection are available on request under ISO 9001:2015.
