Header Bolt Kit - 12pt. 5/16-18 x 1in (12)

The Header Bolt Kit - 12pt. 5/16-18 x 1in (12) from STAGE 8 FASTENERS is designed for serious engine builders and performance mechanics who require reliable fasteners for high-stress applications. These header bolts are essential for securing exhaust manifolds and headers to the engine block, ensuring a leak-free seal under extreme conditions.

Constructed to endure continuous temperatures exceeding 1,000°F, these premium-grade bolts are engineered to handle the thermal cycling and mechanical stress that standard fasteners cannot. The 12-point socket head design provides enhanced clamping force and load distribution, minimizing the risk of stripping and bolt failure during installation and removal.

This kit is ideal for street performance builds, race engines, and restoration projects where reliable fastening solutions are crucial. Mechanics upgrading factory manifolds to aftermarket headers will find these bolts particularly beneficial, ensuring a secure and efficient installation.
