Countersunk Bolt Kit Orange 10pk

The Countersunk Bolt Kit Orange 10pk from ALLSTAR PERFORMANCE is an essential fastener set for engine builders, fabricators, and mechanics performing custom vehicle modifications where aesthetics and function intersect. Countersunk bolts sit flush with mounting surfaces, eliminating protruding heads that can interfere with airflow, catch on components, or create unsightly assembly lines on engine covers and bracket work. Whether you're finishing a custom intake manifold, securing aftermarket timing chain covers, or mounting lightweight components in a high-performance build, this 10-piece kit delivers reliable fastening solutions for both street and competition applications.

Countersunk bolts feature a conical head that angles at approximately 82 degrees, allowing them to nestle completely below the surface when installed into matching countersunk holes. The bright orange finish serves dual purposes: it provides corrosion resistance while offering high visibility in engine bays, making future service and inspection easier. The material composition ensures adequate tensile strength for moderate-load fastening applications typical in engine dress-up, accessory mounting, and custom fabrication work, where vibration resistance and repeatability matter. This particular kit weighs just 0.28 lbs and ships in compact dimensions, making it convenient to keep stocked in your toolbox or shop inventory.

Engine builders and fabricators benefit most from this kit when assembling custom valve covers, timing chain covers, alternator brackets, and decorative engine bay components where OEM fasteners lack the flush-fit profile needed for professional finishes. Countersunk bolts are ideal for lightweight aluminum housings and composite covers where traditional socket-head or hex bolts would protrude awkwardly or create turbulence in forced-induction systems. Installation requires matching countersunk holes—either pre-drilled by component manufacturers or custom-machined to specification—and a countersink bit or deburring tool to match the bolt's 82-degree cone. The 10-piece quantity makes this kit perfect for small-batch builds or maintaining variety in your fastener drawer for impromptu modifications and upgrades.
