Spring SS 316 Stainless Steel Cotter Pins
Torx Drive Delta PT Screws for Plastics
Product Overview
Ensure fail-safe fastening in the harshest environments with our Spring SS 316 Stainless Steel Cotter Pins. Designed for industrial reliability, these pins combine the superior corrosion resistance of Grade 316 stainless steel with a spring-action design to secure bolts, screws, and shafts in high-vibration, high-moisture applications. Perfect for marine, chemical, and automotive systems, they provide a reusable, non-rusting solution for critical connections.
Key Features
- Grade 316 Stainless Steel - Premium marine-grade stainless steel resists pitting, saltwater corrosion, and extreme temperatures, outperforming 304 stainless in harsh environments.
- Spring-Action Design - Flexible, split-ended construction allows easy installation and removal while maintaining constant tension to prevent loosening.
- Universal Compatibility - Fits standard screw heads, bolts, and shafts (metric and imperial) for versatile use in machinery, rigging, and equipment.
- Reusable & Durable - Withstands repeated bending without fracturing, ensuring long-term cost efficiency and reduced downtime.
- Safety Locking - Secures castle nuts, clevis pins, and hydraulic fittings to prevent accidental disengagement in dynamic systems.
- ROHS & REACH Compliance - Free from hazardous substances, meeting global safety and environmental standards.
