Header Bolt Kit - 12pt. 3/8-16 x 1in (16)

The STAGE 8 FASTENERS Header Bolt Kit - 12pt. 3/8-16 x 1in (16-piece set) is designed for engine builders and automotive enthusiasts who require reliable fasteners for their exhaust manifold or header assembly. This kit is particularly useful for those involved in custom engine builds, turbo installations, and high-performance restorations.

Engineered with a 12-point design, these bolts provide superior engagement compared to standard 6-point heads, which helps distribute load evenly and reduces the risk of rounding off during installation and removal. The bolts feature a diameter of 3/8 inch with a thread pitch of 3/8-16 UNC and a length of 1 inch, making them suitable for many modern performance header applications.

Professional engine builders, restoration shops, and dedicated DIY enthusiasts can rely on this kit for assembling stroker motors, LS swaps, and vintage engine restorations. However, it is important to verify compatibility with specific engine types to ensure proper fitment.
