FAQ

What is the 999-30 coiled tension safety pin used for?

The 999-30 safety pin is commonly used to secure spindle axles, heim joints, throttle linkage assemblies and wheel hubs on racing karts or small engines. It offers a fast, secure method of locking components in place during adjustments or operation.


How is this pin different from a cotter pin or hairpin?

Unlike standard cotter pins, the coiled tension design allows for quick removal and reinstallation without tools. It's also more secure than a hairpin cotter, as it resists vibration and accidental dislodging.


What is the usable length of the pin?

The usable length is 0.625 inches, meaning the pin can be inserted through that length of material before the locking coil engages.


Is it reusable?

Yes, the 999-30 coiled safety pin is fully reusable. It’s made from high-tensile spring steel designed to withstand repeated use in high-vibration environments like karting.


Can I use this in place of a standard cotter pin?

Absolutely. In most karting and small engine applications, this pin is a better alternative due to its speed, reliability, and ease of use, especially during quick pit changes or setup tweaks.


Is this pin sold in pairs or individually?
