Technical Data

The Hair Pin Cotter (commonly known as an R-Clip or Spring Cotter) is a versatile, reusable fastener designed for securing clevis pins and shafts. Manufactured from high-grade spring steel with a zinc-plated finish, it offers quick, tool-free installation and reliable retention for agricultural and industrial machinery.

Hair Pin Cotter R-Clip
💪 Spring Steel Construction

Made from high-grade spring steel to ensure the clip maintains consistent tension and grip strength over repeated uses without deformation.

🔗 Double Loop R-Design

The classic R-shape design allows the straight leg to easily insert into the hole while the curved leg securely grips the shaft, preventing accidental fallout.

⚡ Tool-Free Assembly

Designed for fast, manual installation and removal. Ideal for temporary connections or parts requiring frequent maintenance on tractors and mowers.

🛡️ Zinc Plated Finish

Features a durable Zinc Plating (ZP) for excellent corrosion resistance, protecting the pin from rust in harsh outdoor and agricultural environments.

ℹ️ Reusable Solution: Unlike split cotter pins that must be bent and discarded after use, Hair Pin Cotters retain their shape and can be reused multiple times.
ℹ️ Size Range: Available in wire diameters from 2mm to 8mm.

Q: What is the difference between a Hair Pin Cotter and a Split Cotter Pin? A: A Hair Pin Cotter (R-Clip) is made of spring steel and is designed to be reusable and easily removed without tools. A Split Cotter Pin is made of mild steel and must be bent to lock it in place, making it a single-use, semi-permanent fastener.
Q: How do I measure a Hair Pin Cotter? A: The size typically refers to the wire diameter (e.g., 4mm). You should choose a pin with a wire diameter slightly smaller than the hole in your shaft or clevis pin.
