DIN 94 Cotter Split Pin
,Q235 Zinc Plated Carbon Steel
,Anti Vibration Locking Pin
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.
