Rocker Arm Nuts - 7/16

The COMP CAMS Rocker Arm Nuts - 7/16 (SKU COM1401N-16) are precision fasteners engineered for high-performance engine builds where valve train stability under load is non-negotiable. Whether you're assembling a street engine, race motor, or rebuilding a classic with modern cam profiles, these rocker arm nuts secure the rocker arms to the shaft with the correct preload and thread geometry. A loose or undersized fastener in the valve train introduces valvetrain instability, lifter noise, and potential catastrophic engine damage—making OEM-specification hardware critical.

These rocker arm nuts feature a 7/16-20 thread pitch and are constructed from steel with a zinc oxide finish, delivering corrosion resistance and durability in engine compartments exposed to heat cycling and moisture. The set of 16 nuts ensures you have replacements for a full dual-quad or multi-carb application, or a complete small-block build with spares. The zinc oxide coating prevents oxidation while maintaining the precise thread fit required for consistent clamping force—critical for keeping rocker geometry aligned and preventing float under high-RPM conditions. The compact 3.25 x 1.25 x 3.85 inch package (0.53 lbs per set) reflects the compact design typical of small-block fasteners.

Enthusiasts rebuilding traditional Chevy, Ford, Mopar, or Pontiac engines will find these nuts essential for any rocker arm shaft assembly using 7/16-20 thread studs or bolts. These fasteners are compatible with both cast iron and aluminum cylinder heads and work across carbureted and fuel-injected platforms. Torque to manufacturer specification (typically 18–25 ft-lbs for small-block applications) using a calibrated wrench, and verify preload after initial run-in to maintain valve lash and prevent arm walk. Buy this set as insurance against stripped threads or lost fasteners during teardown and reassembly.
