Overview
Our Heavy Duty Linch Pins (Lynch Pins) are robust fasteners designed for quick-connect and quick-release applications. Featuring a spring-loaded round ring attached to a solid carbon steel pin with a square head profile, these fasteners ensure reliable performance under heavy vibrations and high mechanical stress.
Complying with DIN 11023 standards, the spring ring snaps firmly over the end of the shaft or axle, keeping components securely locked during rugged agricultural, industrial, or towing operations.
Key Features & Advantages
- Self-Locking Snap Ring: The integral spring-steel ring provides constant tension, snapping into a secure locked position to prevent accidental pop-outs.
- Heavy-Duty Construction: High-tensile steel pin body resists shearing and deformation under severe load conditions.
- Corrosion Resistance: Available in high-grade Yellow Zinc and White Zinc plating to withstand exterior weather, mud, and harsh environment.
- Tool-Free Fastening: Ergonomic ring design enables easy hand installation and quick manual release without extra tools.
