Overview
ULTRA STRENGTH
In comparison to standard bolts, our alloy's material characteristics enable much higher tensile strength. For the best fatigue strength, threads are rolled after thermal treatment. A high-quality coating can improve corrosion resistance, reduce friction, and improve overall performance.
EASY INSTALLATION
Installation manual is included with drawn diagrams to ease the installation process. Our head bolts are designed to retain cylinder seal even with today's extremely high-pressure turbo systems.
PREMIUM QUALITY
Black oxide finish protects from wear and tear. Hardened parallel washers allow for uniform load distribution and accurate torque readings.

Engineering details
Small details. A secure assembly.
The bolt head bears on a hardened washer while the threaded end engages the engine block. Tightening the bolt creates the clamping load that holds the cylinder head and gasket against the block.
XOTIC 7200 alloy.
Alloy steel head bolts with a black oxide finish, paired with hardened parallel washers.
Threads rolled after treatment.
The bolt threads are rolled after thermal treatment as part of the manufacturing process.
A matched seating surface.
Hardened parallel washers sit beneath the bolt heads and distribute load across the seating surfaces. Use the supplied assembly lubricant with the correct procedure for your kit.
