Cotter Pins, also known as split pins, are simple yet essential fasteners used to secure components on axles, shafts, or bolts. Made from a single piece of semi-ductile metal wire bent into a loop with two tines that spread apart after insertion, they provide a reliable, removable mechanical lock that prevents nuts or parts from loosening or sliding off under vibration.

Typical Applications:

• Axle & Shaft Retention: Securing wheels, gears, and linkages on clevis pins or castellated nuts in automotive, agricultural, and machinery assemblies.

• Safety Critical Connections: Used in steering linkages, control mechanisms, and suspension systems where a fail-safe lock is paramount.

• General Industrial Fastening: Providing a quick and secure locking solution for a wide range of industrial equipment and hardware.

Our Product & Capabilities:
We supply cotter pins in various materials including low-carbon steel, stainless steel, and brass. Our standard range covers multiple diameters and lengths to fit common clevis and castle nut sizes. We also support customization focused on:

• Material & Finish: Selection of base material and finishes (e.g., zinc plating, passivation) for optimal strength and corrosion resistance.

• Precision Dimensions: Custom pin diameter, overall length, and head design to meet specific assembly requirements.

• Packaging: Options for bulk or pre-sorted packaging to suit production line needs.

Our cotter pins offer a cost-effective and universally trusted solution for ensuring the integrity and safety of critical mechanical connections.
