Header Bolt Kit - 6pt. 3/8-16 x 3/4 (16)

The Header Bolt Kit - 6pt. 3/8-16 x 3/4 (16) by STAGE 8 FASTENERS is a professional-grade fastener set engineered for high-performance engine builds and custom automotive applications. This 16-piece bolt kit is designed for operators and builders who demand precision hardware that withstands extreme conditions—whether you're assembling a race engine, performing critical engine work, or building specialized tactical vehicle platforms. Header bolts are mission-critical fasteners that must resist vibration, heat cycling, and lateral stress that would compromise inferior hardware.

Each bolt in this kit features a 6-point head design, which provides superior contact surface and reduces the risk of rounding compared to conventional 12-point designs—a critical advantage in high-vibration environments. The 3/8-16 thread specification indicates a 3/8-inch diameter with 16 threads per inch, delivering optimal clamping force and torque retention for header flange applications. STAGE 8 FASTENERS are manufactured to exacting tolerances using premium materials selected for thermal stability and fatigue resistance. The 3/4-inch length accommodates standard header flange thickness, ensuring proper engagement without bottoming out or causing joint separation under operating stress.

This header bolt kit is ideal for engine builders, motorsports professionals, and DIY enthusiasts performing header installation or replacement on performance vehicles. The 6-point head specification is particularly valuable in tight engine bay environments where socket engagement is critical and stripped fasteners are unacceptable. Installation requires proper torque sequencing and appropriate torque values for your specific application—consult your engine build documentation or manufacturer specifications for exact torque settings. These bolts are suitable for both street and competition applications where reliability and repeatability are non-negotiable. The complete 16-piece set eliminates the need to source individual fasteners, ensuring consistency across all header mounting points.
