DIN 94 Split Pins for automotive industry, car parts Cotter pins ASME B 18.8.1 zinc-plated

Our DIN 94 and ISO 1234 compliant split pins (also known as cotter pins) are simple yet highly effective mechanical fasteners designed for quick and manual installation. Featuring a cylindrical body with a lengthwise slot, these pins offer inherent elasticity. To install, simply insert the pin into a pre-drilled hole of the corresponding nominal diameter and then spread the two ends apart using pliers or a hammer to create a secure locking mechanism. This straightforward process makes them a time-efficient and user-friendly solution for various automotive assembly needs.

Key Advantages for Your Automotive Applications:

• Secure Assembly Locking: Acting as a reliable mechanical lock, split pins effectively prevent nuts, bolts, and other components from accidentally loosening, especially in environments prone to significant vibrations and repeated shocks common in vehicles.
• Simplified Installation & Removal: Their basic design allows for manual insertion and spreading, requiring minimal tooling (typically just pliers). Removal is equally straightforward by simply straightening and pulling out the spread ends.
• Versatile Application Range: Available in a wide array of diameters (Ø1.5 to Ø25 as standard, with custom options available), split pins can be used across numerous automotive sub-systems, from securing wheel bearings to fastening linkages.
• Cost-Effective Reliability: Manufactured in durable zinc-plated steel as standard, they offer a cost-efficient yet dependable fastening solution for many automotive applications. Optional materials like stainless steel (for enhanced corrosion resistance in exposed areas), aluminum bronze, or copper are available upon request for specialized environments.
• Compliance with Industry Standards: Manufactured according to DIN 94 and ISO 1234 standards, ensuring dimensional accuracy and material properties that meet stringent automotive industry requirements for safety and reliability.

Ideal for Automotive Applications Such As:

• Wheel Bearing and Axle Securing: Preventing the axial movement and loosening of nuts on wheel axles and bearing assemblies.
• Steering and Suspension Linkages: Locking clevis pins and other pivot points in steering arms, tie rod ends, and suspension components to ensure operational integrity.
• Brake System Fastening: Securing critical pins and levers within the braking mechanism, ensuring safety and reliability.
• Transmission and Gearbox Assemblies: Preventing the loosening of shafts, gears, and other rotating components within the powertrain.
• Exhaust System Mounts: Locking bolts and pins in exhaust hangers and brackets, especially in areas subject to vibration and heat.
• Body Panel and Trim Attachment: Securing certain non-critical body panels, clips, and trim pieces where a simple and reliable locking mechanism is sufficient.
• Agricultural and Off-Highway Vehicles: Fastening components in machinery and vehicles operating in demanding and high-vibration environments.
• General Mechanical Assemblies: Used throughout the vehicle for securing various pins, shafts, and other moving or stationary parts where a simple and effective locking solution is needed.
