Countersunk Bolt Kit Red 10pk

The Countersunk Bolt Kit Red 10pk from ALLSTAR PERFORMANCE delivers a complete fastening solution purpose-built for automotive assembly, restoration, and precision mechanical work. Designed for professionals who demand reliability under stress, this kit combines allen head bolts, countersunk washers, and locking hardware in a single package—eliminating trips to the hardware store and ensuring component compatibility across your build. The red finish provides visual distinction for critical connections, making assembly verification and maintenance faster in high-workload environments.

Each fastener in this countersunk bolt kit features 1/4-20 thread specification with a 1-inch length, engineered for shallow countersink applications where flush mounting is essential. The kit includes allen head cap screws paired with countersunk washers—a design that distributes load across a wider surface area and prevents bolt head pull-through on softer materials. Steel construction with zinc oxide plating delivers corrosion resistance suitable for both shop and field conditions, while the included lock nuts provide positive thread engagement and eliminate vibration-induced loosening during operation. This combination of materials and hardware ensures sustained clamping force even in high-vibration applications typical of motorsports and heavy equipment assembly.

Technicians, fabricators, and restoration specialists rely on complete fastening kits to streamline assembly workflows and reduce part sourcing delays. The ten-piece configuration covers standard sub-assemblies and provides spares for field repair or rework—critical for professionals managing multiple projects simultaneously. Installation is straightforward: insert the countersunk washer before threading the bolt into place, then secure with the lock nut hand-tight, then torque to specification using a standard hex wrench. Compatible with any component accepting 1/4-20 fasteners, this kit integrates seamlessly into existing builds and serves as reliable backup stock for shops maintaining motorsports platforms, chassis work, or mechanical systems requiring secure, vibration-resistant joints.
