OPTITORQUE HEAD BOLT KIT - 1997-2003 LS ENGINES - 10574

Every OptiTorque fastener is crafted from domestically melted American HIGH STRENGTH STEEL. Each fastener is then heat treated in our vacuum furnaces and undergoes a proprietary tempering process to achieve an optimized fine grain structure. Post processing operations such as centerless grinding, ensure each fastener is perfectly concentric prior to thread rolling. Each fastener(s) application is engineered to maximize the joint clamp load requirements without compromise. These premium fasteners offer an exceptional strength-to-value ratio, making this series of fasteners the professional’s choice and the industry leader in its price class. The studs also feature a recessed hex to aid with installation and removal. Each fastener is hot temperature oiled and brilliant black oxide coated for protection. This kit contains forged high-strength heat treated 12-point nuts, and precision ground load distributing washers, ensuring a uniform clamp load.  Every kit contains True Torq+ (reg trademark), fastener-assembly lubricant, installation procedures, and a warranty information card. 100% manufactured with pride in the USA. Our Patriot series fasteners are a minimum of 210,000psi UTS.
