OVERVIEW
Dynofit cylinder head fasteners are built from premium 8740 high-tensile chromoly steel, cold-forged for superior molecular integrity, then heat-treated before thread rolling and precision-machined to ensure consistency. Rated at 190,000 psi tensile strength, the kit includes 12-point nuts and hardened parallel washers for even load distribution, secure clamping, and repeatable, precise torque—helping maintain gasket seal and long-term reliability under high stress.
