Installed on the connecting rod bolts at the big end, this nut provides the required clamp load to keep the rod assembly rigid under combustion forces and inertia at speed. Built to OEM-style dimensions (commonly listed as M10), it supports accurate torqueing and secure retention under high RPM loads and repeated heat cycles - ideal for rebuilds, top-end refreshes, or bottom-end assembly work.
Con-rod fasteners live in one of the harshest areas of the engine. Nuts can be damaged, corroded, or compromised by previous over-torqueing or repeated reuse. Replacing with OE Match hardware helps ensure accurate torque application and dependable clamp load retention - critical for bearing life and engine reliability.
When to replace:
• During any engine rebuild involving connecting rod removal
• Nuts show thread damage, rounding, corrosion, or heat marking
• Evidence of incorrect prior assembly/torque history
• Preventive replacement on high-mileage or unknown-history engines
