Diaper Pin 2-3/4in

The Allstar Performance Diaper Pin 2-3/4in is a heavy-duty safety fastener designed for securing engine components, hood pins, and critical mechanical assemblies during high-performance driving or racing conditions. This compact yet rugged fastener serves as a backup retention system, preventing hoods, doors, or vital parts from opening unexpectedly under extreme acceleration, braking, or track use.

Manufactured by Allstar Performance, this pin is machined from hardened steel to withstand repeated stress cycles and vibration. The compact 0.8-inch diameter shaft allows secure insertion through pre-drilled holes while maintaining minimal protrusion, and the total weight of just 0.03 lbs ensures negligible impact on vehicle balance or performance. The design is critical for maintaining component integrity under cornering loads or sudden directional changes.

This diaper pin is ideal for street rodders, race mechanics, engine builders, and enthusiasts who demand fail-safe retention in their custom builds. Whether you're building a street machine or preparing for weekend track events, this fastener provides the mechanical security that separates a reliable build from a dangerous failure.
