COMP Cams Stud Girdle Adjusting Nuts (7/16-20) are precision-engineered fasteners designed to secure rocker arm studs and stud girdles on high-performance engines. These adjusting nuts are essential for any serious builder or mechanic working with aftermarket cylinder head assemblies, particularly in applications requiring precise preload control and repeatability. Whether you're assembling a stroker engine, upgrading a stock head, or rebuilding a race-ready power plant, these nuts ensure your valve train components remain secure under extreme rpm and load conditions.
The 7/16-20 thread pitch specification provides optimal clamping force distribution without over-tightening, which can strip studs or crush rocker arm geometry. COMP Cams manufactures these nuts to exacting tolerances, ensuring consistent wrench fit and preventing thread galling during installation. The fastener design accommodates proper rocker arm preload adjustment—critical for maintaining valve lash consistency and preventing valve float at high engine speeds.
Quality construction resists loosening from vibration and thermal cycling, protecting your investment in premium rocker arms and stud girdle systems. These adjusting nuts are compatible with COMP Cams rocker arm studs and most aftermarket stud girdle kits used in small-block and big-block applications. Professional engine builders and weekend enthusiasts alike rely on this product when rebuilding cylinder heads or transitioning from factory rockers to aftermarket solutions.
