Clevis Pin Carbon Steel — Factory Direct Supplier | Huaxia-Steel
Clevis pins are cylindrical fasteners with a head at one end and a cross-hole at the other, designed to secure clevis fittings, linkages, and pivoting connections in mechanical and structural assemblies. Huaxia-Steel supplies carbon steel clevis pins manufactured to international specifications with reliable mechanical properties and consistent dimensional accuracy for OEM, agricultural, construction, and marine applications.
Product Overview
A clevis pin consists of three key features: a cylindrical shank that passes through aligned holes in mating components, a head (flat, dome, or hex) that retains the pin on one side, and a cross-drilled hole near the opposite end that accepts a cotter pin, split pin, or R-clip to secure the assembly. This simple but effective design allows rapid assembly and disassembly without tools, making clevis pins ideal for applications requiring frequent connection and release.
Huaxia-Steel carbon steel clevis pins are hot-forged or cold-headed from quality carbon steel wire and bar stock, then machined to final dimensions. We offer standard and custom sizes with various head styles, surface finishes, and material grades to match your application requirements.

Manufacturing Standards
Huaxia-Steel clevis pins are produced to the following international specifications:
- ISO 2340: Clevis pins with head — the primary international standard. Defines dimensions, tolerances, and material requirements for clevis pins with diameters from 3mm to 100mm.
- ISO 2341: Clevis pins with head (metric series, types A and B) — specifies head styles: Type A (without hole in head), Type B (with hole in head).
- DIN 1445: Clevis pins with head and threaded portion — for clevis pins with a threaded end instead of a cross-hole.
- DIN 1433: Clevis pins without head — plain cylindrical pins with cross-holes at both ends.
- ASME B18.8.1: Clevis Pins and Cotter Pins (Inch Series) — American standard specifying imperial dimensions.
- BS 2470: Specification for hexagon socket screws and wrench keys — referenced for imperial-dimensioned clevis assemblies.
Material test certificates to EN 10204 Type 3.1 (specific inspection) or ASTM MTR format are provided as standard. Third-party inspection (EN 10204 Type 3.2) by SGS, Bureau Veritas, TÜV, or Lloyd’s Register is available upon request.
Applications
Carbon steel clevis pins are essential components in numerous industries:
- Agricultural equipment: Three-point hitch pins, implement attachment pins, drawbar connections. C45/1045 carbon steel with zinc plating provides an optimal balance of strength and corrosion protection for outdoor agricultural service.
- Construction machinery: Hydraulic cylinder clevis mounts, loader arm pivots, backhoe linkage pins. Q&T 4140 pins with induction-hardened surfaces for extended wear life under heavy loads with abrasive contamination.
- Material handling: Forklift mast tilt cylinder pins, conveyor pivot connections, crane hook clevis assemblies. High-strength pins with safety-retained cotter pins prevent accidental disconnection.
- Marine/offshore: Rigging connections, lifeboat davit pins, hatch cover clevis assemblies. Hot-dip galvanized or stainless steel pins for corrosion resistance in saltwater exposure.
- Railway: Brake linkage connections, coupler clevis pins, suspension pivot points. Certified material with full traceability and periodic NDT.
- Automotive/transport: Trailer hitch pins, tow bar connections, suspension linkage pivots, fifth-wheel kingpin assemblies.
