Countersunk Bolt Kit Purple 10pk

The Countersunk Bolt Kit Purple 10-pack from ALLSTAR PERFORMANCE is a precision fastener assembly designed for applications requiring secure, flush-mounted connections. Each kit includes 1/4-20 inch thread bolts cut to 1 inch length, matched countersunk washers, and lock nuts—all finished in purple zinc oxide coating. This complete fastener kit delivers the threaded reliability and corrosion resistance critical to automotive, motorsports, and equipment assembly where bolt security cannot fail.

The 1/4-20 thread specification offers balanced holding power across a wide range of fastening tasks, while the 1 inch length accommodates standard assembly depths. Allen head socket design permits torquing without slipping and supports repeatable tightening cycles—essential where vibration or thermal cycling demands consistent clamp load. The zinc oxide coating provides baseline corrosion protection, though salt-air or high-moisture environments may require periodic inspection. Countersunk washers distribute clamping load while allowing flush installation on prepared surfaces, eliminating interference with moving components or mating parts.

This 10-pack format suits fabricators, restoration shops, race teams, and equipment manufacturers who standardize on 1/4-20 fastening and require predictable inventory. The purple finish aids visual identification in mixed-fastener environments and allows color-coded assembly procedures. Included lock nuts prevent fastener loosening under normal operating vibration, eliminating the need for additional threadlocker compound on routine applications. Stock this kit for brake assemblies, carburetor mounts, accessory brackets, and any critical bolted joint where flush fit and secure retention matter.
