Bolt Flywheel 7/16-20 x 1in 6 Pcs.

The Bolt Flywheel 7/16-20 x 1in 6 Pcs kit from Coleman Racing Products is engineered for high-performance engine builders and mechanics performing flywheel installation, replacement, or upgrade work on racing and street applications. These fasteners secure the flywheel to the crankshaft flange, a critical connection that directly impacts engine balance, drivability, and power delivery to the transmission. Whether you're rebuilding a stock engine or assembling a custom racing powerplant, this bolt kit ensures a reliable, torque-holding clamping load that won't slip under sustained acceleration or load cycling.

Each fastener is sized at 7/16-20 with a 1-inch length, a geometry optimized for standard flywheel bolt holes across many domestic and imported platforms. The 7/16-inch diameter combined with the fine 20 threads-per-inch pitch provides excellent clamping stiffness while minimizing stress concentration at the crankshaft flange. Coleman Racing Products manufactures these bolts to exacting standards, ensuring consistent tensile strength and fatigue resistance through repeated engine cycles. The six-piece set covers a complete flywheel mounting pattern, reducing the need for separate sourcing and guaranteeing matched hardware that locks in uniform preload during installation.

This bolt kit is ideal for engine rebuilders, transmission specialists, and performance enthusiasts installing or replacing flywheels on manual-transmission vehicles, drag racing platforms, and high-output street engines. Proper torque sequencing and application of a quality thread-locking compound ensure maximum holding power and prevent vibration-induced loosening. Always verify bolt length and thread pitch against your specific engine block and flywheel design before installation to guarantee proper engagement and avoid bolt bottoming or insufficient thread grip.
