Introduction
316 Stainless Steel Cotter Pin is a dual-tine metal locking fastener used for securing nuts, bolts, and clevis pins in mechanical assemblies.
Our Core Product Assets
Superior Corrosion Resistance
Marine-grade AISI 316 steel with added Molybdenum maintains a rust-free surface in high-salinity and acidic environments.
High Ductility
Soft-tempered stainless steel metallurgy permits multiple 90-degree tines bending cycles without localized cracking or material snapping.
Precision Sizing
Cold-formed bodies with strict diameter tolerances ensure a slide-fit entry into pre-drilled holes with zero radial jamming.
Easy Handling
The smooth semi-circular profile and standardized loop head allow for rapid manual insertion and simple plier-based removal.

Safety & Compliance
Safety Performance
Anti-Shedding Lock
Once the tines are bent, they form a solid mechanical stop that prevents any axial movement or accidental drop-off of the fastener.
Non-Magnetic Safety
The 316 austenitic structure produces no magnetic spark or interference, ensuring total safety in precision electronic and explosive environments.
Standards Compliance
Technical Standard
Fully compliant with GB/T 91 and international DIN 94 / ISO 1234 dimension criteria.
Material Grade
Guaranteed AISI 316 / SUS 316 stainless steel with full material traceability and mill test reports.
