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. This kit is ideal for fabricators, restoration shops, race teams, and equipment manufacturers who standardize on 1/4-20 fastening and require predictable inventory.

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. The Allen head socket design allows for torquing without slipping, ensuring consistent clamp load in environments subject to vibration or thermal cycling. The zinc oxide coating provides baseline corrosion protection, although environments with salt-air or high moisture may require periodic inspection.

The countersunk washers distribute clamping load while allowing flush installation on prepared surfaces, eliminating interference with moving components or mating parts. The purple finish aids visual identification in mixed-fastener environments and supports color-coded assembly procedures, making it a practical choice for various assembly tasks.
