Wheel Studs 12mmx2.500 .505 Knurl 10pk

The Moser Engineering Wheel Studs 12mm x 2.500 .505 Knurl 10-pack (MEI8255) delivers OEM-grade fastening hardware for high-performance engine builds and street/strip applications. These steel studs feature black oxide finish for corrosion resistance and precise 12mm threading that locks consistently through repeated assembly and disassembly cycles—critical when you're running high horsepower or frequently pulling a cylinder head for tuning adjustments.

Each stud measures 2.500 inches in length with a 0.505-inch knurl diameter, engineered to seat properly in block bosses and deliver uniform clamp load when torqued to specification. The black oxide coating provides a thin protective layer that resists rust without adding bulk—important for tight engine compartments and applications exposed to moisture or salt environments. A 10-pack quantity covers most standard small-block rebuild scenarios, whether you're refreshing a single head or building a complete long-block assembly.

These studs suit engine builders, performance shops, and enthusiasts tackling head gasket replacement, engine overhaul, or rotating assembly work. The precision manufacturing ensures compatibility with aftermarket cylinder heads, OEM blocks, and both carbureted and fuel-injected applications. Moser Engineering's reputation in the engine building supply market reflects attention to thread geometry and material consistency—factors that directly impact gasket sealing integrity and long-term reliability.

Whether you're assembling a stock rebuild or a high-compression performance engine, having quality studs with predictable clamp characteristics eliminates variables during torque sequencing. The 10-pack format provides working inventory without excessive surplus, making it practical for both one-off projects and shops managing multiple builds simultaneously.
