Anti-Slip Flange Design: The integrated hex flange head distributes pressure evenly to prevent loosening under vibration. It offers maximum tool grip for high-torque application, eliminating rounding and slipping during installation or removal in confined spaces.

Precision Sealing Threads: Features roll-formed threads for a clean, sharp, and consistent fit. This precision machining ensures perfect engagement with factory threads, reducing cross-threading risk and creating a reliable, leak-free seal from the first turn.

Premium Material: Crafted from Grade 8 High-Strength Carbon Steel, this exhaust manifold bolt provides exceptional tensile strength and fatigue resistance, engineered to withstand extreme exhaust heat cycles and constant vibration without warping.

Corrosion-Resistant Coating: The gold iridescent zinc plating provides a robust barrier against rust, corrosion, and oxidation. This ensures long-term durability under the hood and guarantees the bolts remain functional and easy to remove for years to come.

Complete Replacement Kit: This 10-piece bolt and nut kit in 0.7" x 1.45" size offers a complete solution for exhaust manifold and other high-temperature repairs. It serves as a direct OEM replacement for most car, truck, and SUV models.
