Speedmaster Connecting Rod Bolts - Steel

Speedmaster steel connecting rod bolts, also called rod bolts or con rod fasteners, are made for performance and racing engine builds. They are precision CNC-machined to exacting specifications and designed for optimum reliability. They replace stock rod fasteners where more clamping strength is needed.

Key Features:

• Fatigue strength: The bolts are heat-treated and the threads are rolled, giving up to ten times more fatigue strength.
• High yield strength: They are rated at 200,000 psi yield strength.
• Chromoly steel construction: The line uses chromoly steel, with 8740 chromoly used in the 12-point cap screw bolts.
• Precision machining: CNC machining keeps dimensions consistent, so the bolts clamp the rod cap securely and evenly.

Compared with standard OEM fasteners, these bolts are far more durable and can handle the extra stress of high-combustion engines. They suit performance street, stroker, and racing engine builds. Use them when rebuilding or upgrading a rotating assembly, and follow the engine builder's torque specifications and procedures.
