DIN 94 Cotter Pin Split Pin Carbon Steel & Stainless Steel M1.6-M20

Our DIN 94 cotter pins (also known as split pins) are precision-formed two-prong fasteners used to lock bolts, shafts and clevis pins in place, preventing nuts and pins from vibrating loose. 

• Three international standards — DIN 94 / ISO 1234 / ASME B18.8.1, fully interchangeable with standard fittings, metric and imperial full series.
• Dual material grades — Q195 / Q235 carbon steel economy grade plus SS304 / SS316 stainless for corrosive environments.
• Multiple surface finishes — zinc plating (white / blue / yellow), black oxide or plain, to suit indoor and outdoor use.
• Reliable anti-loosening — locks bolts and clevis pins against vibration withdrawal for dependable safety.

Cotter pins are widely used to secure clevis pins, castle nuts, hinge pins and rigging hardware. Typical applications include automotive chassis and suspension, agricultural machinery articulation, marine and ship rigging, and hinge pin retention where a reliable, easy-to-inspect locking device is required.

Each batch is dimensionally inspected and material test reports are available upon request. 

Products are packed in export-grade cartons on fumigated wooden pallets, suitable for long-distance sea freight. Custom packaging, private labeling and OEM sizes are available for bulk orders.
