Countersunk Bolt Kit Blue 50pk

The Countersunk Bolt Kit Blue 50-pack from Allstar Performance delivers a complete fastening solution for assembly, repair, and fabrication work where precision hardware is essential. This 50-piece set includes 1/4-20 inch thread countersunk bolts at 1 inch length, paired with matching countersunk washers and lock nuts—everything needed for secure, flush-mounted fastening in a single kit.

Each bolt features an Allen head (hex socket) design for controlled torque application and reduced rounding risk during installation and removal. The kit combines steel hardware with zinc oxide and blue protective finishing to resist corrosion during storage and moderate-duty use. The countersunk washer design allows bolts to sit flush with mounting surfaces, eliminating proud fastener protrusion—a critical detail for applications where surface integrity or aerodynamic profile matters. The included lock nuts prevent vibration-induced loosening, a common failure point in equipment subjected to field use or repeated handling.

This kit serves mechanics, technicians, and field operators who need reliable hardware for equipment assembly, tactical gear modification, vehicle repair, or equipment fabrication. The 1/4-20 thread size is a standard fastener specification across automotive, aerospace, and industrial applications, making replacement bolts and matching hardware widely available if the kit is partially consumed. The 50-piece count provides adequate inventory for typical project builds or serves as a replenishment stock for maintenance operations.

Allstar Performance is recognized for precision fastening solutions in motorsport and mechanical assembly environments. This kit's combination of flush-mount design, lock nut inclusion, and corrosion-resistant finish makes it suitable for applications where fastener reliability cannot be compromised and where finished appearance demands concealed hardware.
