1/4-20 X 1 3/8In Stud Set Of 4

The 1/4-20 X 1 3/8In Stud Set Of 4 by Racing Power Co-Packaged is a precision valve cover fastener engineered for engine builders and restoration enthusiasts who demand reliable, professional-grade hardware. These studs replace or supplement standard valve cover bolts on classic and modern engines, providing a cleaner aesthetic while maintaining secure fastening under high vibration and thermal cycling. Available as a set of four, this product addresses the need for replacement fasteners that match OEM specifications and performance standards.

Machined from steel and finished in black oxide, the 1/4-20 X 1 3/8In Stud Set Of 4 delivers corrosion resistance and a clean, finished appearance that complements engine bay presentation. The 1/4-20 thread specification ensures compatibility with standard 1/4-inch fastener hardware, while the 1.375-inch length accommodates typical valve cover mounting applications without requiring custom spacers or washers. Black oxide plating not only protects against surface rust and oxidation but also reduces light reflection for a professional factory look. Steel construction provides the strength necessary to withstand repeated thermal expansion and vibration cycles inherent to engine operation.

Engine builders, hot rod and classic car restorers, and DIY mechanics benefit most from this stud set when upgrading from worn OEM fasteners or standardizing valve cover hardware across an engine bay. Installation is straightforward—simply thread the studs into existing tapped holes on the valve cover or engine block, then secure with matching washers and nuts. The set of four covers one complete valve cover on most four-cylinder and small-block engines, making it an economical choice for both single-engine projects and fleet maintenance applications.
