Stainless Steel Split Pins for Secure, Vibration-Proof Fastening

Our Stainless Steel Split Pins provide a simple yet highly reliable method for securing castellated nuts, clevis pins, and other critical connections. Manufactured from corrosion-resistant stainless steel, these pins feature two pre-formed legs that spring back after installation, creating a positive lock that withstands vibration and shock. Designed for quick installation without special tools, they offer a cost-effective solution for preventing fastener loosening in applications ranging from marine rigging to heavy machinery.

Product Specifications

Product Applications

Stainless Steel Split Pins are essential safety fasteners used wherever mechanical connections must resist loosening under dynamic conditions.

1. Marine and Boating: Secures propeller shafts, rudder linkages, and rigging components against saltwater corrosion and constant vibration.

2. Automotive and Heavy Equipment: Locks castellated nuts on wheel spindles, suspension components, and steering linkages in trucks, trailers, and agricultural machinery.

3. Aerospace and Aviation: Used in control cable connections and critical fastener assemblies where absolute reliability is mandatory.

4. Industrial Machinery: Prevents clevis pins and shaft collars from backing out in conveyors, presses, and construction equipment.

5. General Maintenance and DIY: Ideal for securing hitch pins, bicycle axles, lawn mower blades, and countless repair applications.

Product Advantages

Choosing our stainless steel split pins means selecting a fastener that delivers lasting security with minimal installation effort.

1. Superior Corrosion Resistance: A2 and A4 stainless steel grades withstand rain, salt spray, and chemicals, eliminating rust stains and ensuring long service life even in harsh outdoor or marine environments.

2. Vibration-Proof Locking: The spring-action legs spread after insertion, creating a secure hold that prevents castellated nuts and clevis pins from loosening under constant machine vibration or shock loads.

3. Simple, Tool-Free Installation: Requires only finger pressure to insert and a simple bend to secure; no wrenches, torque specifications, or specialized training needed.

4. Cost-Effective Safety Solution: Provides critical fail-safe protection at a fraction of the cost of more complex locking mechanisms, making it an economical choice for both OEM and maintenance applications.

5. Visually Inspectable: Installed pins can be checked at a glance, allowing for quick safety verification during routine equipment inspections.

Product Features

Our stainless steel split pins incorporate design details that ensure reliable performance and compatibility with standard hardware.

1. Precision Formed Legs: Manufactured to tight dimensional tolerances, ensuring the legs slide smoothly through drilled holes in bolts, shafts, and nuts without binding or forcing.

2. Spring-Temper Resilience: Made from fully annealed stainless steel wire that maintains consistent spring-back action, providing a secure grip even after multiple installations in non-critical applications.

3. Wide Size and Length Range: Available in diameters from 1/16" to 1/2" and lengths up to 6", allowing precise matching to hole diameters and fastener sizes for maximum holding strength.

4. Compliant with International Standards: Manufactured to meet ASME B18.8.1, ISO 1234, and DIN 94 specifications, ensuring interchangeability with standard castellated nuts and clevis pins.

5. Multiple Leg Configurations: Offered with equal or unequal leg lengths to accommodate different installation preferences and access constraints in tight spaces.

6. Traceable Material Options: Material test reports and certifications available for applications requiring documented material provenance
