Detailed Description
Overview
Our R Clips (Hairpin Cotter Pins) are engineered for fast, secure, and reliable temporary or permanent locking solutions. Manufactured in strict accordance with DIN 11024 standards, these spring pins feature an ergonomically curved leg that snaps over shafts or clevis pins to prevent unintentional dislodging caused by vibration.
Unlike traditional split cotter pins, R clips are fully reusable and can be quickly installed or removed without requiring special tools, making them the ideal choice for applications requiring frequent maintenance or adjustment.
Key Features & Advantages
- High-Elasticity Spring Wire: Made from premium spring steel with heat treatment, offering excellent resiliency, memory, and fatigue resistance under high stress.
- Superior Corrosion Resistance: Smooth zinc plating or stainless steel options provide outstanding protection against rust, moisture, and chemical exposure.
- Easy & Fast Installation: Designed with an angled end tip that slides smoothly over shafts, snapping firmly into the designated retention hole.
