7/16in-20 Wheel Studs .480in Knurl

The 7/16in-20 Wheel Studs .480in Knurl from MOROSO are precision-engineered fasteners designed specifically for late-model GM drum brake applications. These studs are the critical link between your wheel hub and rim, responsible for safely transferring all cornering, acceleration, and braking loads directly to the road surface. Whether you're rebuilding a classic GM muscle car, restoring a vintage truck, or upgrading a performance suspension, quality wheel studs are non-negotiable—inferior fasteners lead to wheel separation, a catastrophic failure no driver can recover from.

Each stud features a 7/16-20 thread pitch with a 0.480-inch knurl diameter, engineered to mate precisely with OEM GM drum brake hardware and ensure consistent clamping force across the lug circle. The black oxide finish provides corrosion resistance and a professional appearance while protecting the steel substrate in harsh road conditions. The 2.875-inch length is calibrated for proper thread engagement and wheel-to-hub clearance, preventing bottoming-out and ensuring even load distribution across all five studs in the set. MOROSO's manufacturing tolerances are held tight, guaranteeing that each stud meets specification for concentricity and thread geometry—critical for eliminating vibration and maintaining brake balance.

Mechanics and enthusiasts rely on these studs when replacing worn or damaged fasteners in drum brake setups common to 1960s–1980s GM vehicles. Installation is straightforward: press out the old studs, install the new set (torque specifications vary by hub design), and verify wheel runout before road use. A set of five covers one wheel; consider purchasing multiple sets if servicing multiple vehicles or keeping spares for track events. Whether you're a DIY restorer or a professional shop, MOROSO's reputation for dimensional accuracy means these studs will perform reliably through years of street and performance driving.
