Stainless Steel Retaining Split Pins Marine Grade Cotter Pins

The Retaining Split Pins Stainless Steel are premium marine-grade cotter pins designed for securing clevis pins, castellated nuts, shafts, rudder fittings, trailer hardware, and marine fastening systems in demanding New Zealand conditions. Manufactured from corrosion-resistant stainless steel, these split retaining pins provide reliable fastening security, excellent durability, and long-lasting performance in harsh saltwater and outdoor environments.

Featuring a traditional split-pin design, these retaining pins are inserted through pre-drilled holes in fasteners or shafts and then bent to lock components securely in place. Stainless steel split pins are widely used in marine engineering, yacht rigging, trailer maintenance, automotive applications, agricultural equipment, and general mechanical fastening where dependable removable locking is required. Stainless split pins are commonly specified for marine use because they provide excellent corrosion resistance and secure mechanical retention.

The marine-grade stainless steel construction resists rust, oxidation, and saltwater corrosion, making these retaining split pins ideal for offshore boating, coastal environments, trailer assemblies, and outdoor engineering projects. Their simple yet highly effective design allows quick installation and easy servicing while maintaining strong retention under vibration and movement.

Suitable for use with clevis pins, axle nuts, marine hardware, steering systems, trailer hubs, rudder fittings, and rigging systems, these stainless retaining split pins are an essential marine fastening component for professional and DIY applications alike.
