1/4 x 1.500 Valve Cover Stud w/Bullit Nose

The 1/4 x 1.500 Valve Cover Stud w/Bullet Nose from ARP is an essential fastening solution for serious engine builders and performance enthusiasts who demand reliability under extreme conditions. Designed to replace factory valve cover fasteners, this stud eliminates the inconsistency of traditional bolts and provides superior clamping force control—critical when working with aluminum or composite valve covers that are prone to warping.

ARP's signature design features a 1/4-inch diameter stud with a distinctive bullet nose (rounded tip), which prevents thread galling and ensures smooth, controlled installation without cross-threading risk. The 1.500-inch length accommodates standard valve cover gasket thickness while providing ample thread engagement for a tight, leak-free seal. Manufactured from premium ARP material, these studs resist corrosion and maintain their clamping load even in high-heat engine bays.

This valve cover stud is ideal for engine rebuilds, custom builds, and any application where you're replacing factory fasteners. The bullet nose profile also reduces stress concentration at the gasket surface, extending gasket life and minimizing oil seepage—a common failure point with inferior fasteners. Whether you're building a street engine or preparing a competition platform, ARP studs deliver the precision and durability required to keep your cylinder head sealed tight across thousands of heat cycles.
