1/2-20 x 1-1/2 Wheel Studs (10pk) .665 Knurl

The Moser Engineering 1/2-20 x 1-1/2 Wheel Studs (10-pack) with .665 knurl diameter are precision-engineered fasteners designed for high-performance wheel applications and street rod builds. These steel studs feature a zinc oxide finish for corrosion resistance and are manufactured to exacting tolerances that ensure proper wheel mounting security and repeatability across multiple installations.

The 1/2-20 thread specification (1/2-inch diameter with 20 threads per inch) is a standard specification found on many performance and custom applications. The 1.500-inch length provides sufficient engagement depth for most contemporary wheel hub designs. The .665-inch knurl diameter is critical for lug nut fit and load distribution—the knurled section locks the stud in place while the smooth shank allows precise alignment during wheel mounting. This geometry is essential for preventing stud rotation during installation and ensuring consistent clamping force around the wheel perimeter.

Moser Engineering wheel studs are favored by builders and technicians working on custom, modified, and street rod vehicles where OEM studs are unavailable or inadequate for upgraded brake and suspension systems. The 10-pack quantity supports either a complete wheel set or a partial replacement scenario. These studs perform under the thermal cycling and vibration conditions common to performance driving, autocross, and weekend track sessions.

Proper wheel stud selection is fundamental to vehicle safety—mismatched or substandard fasteners can lead to wheel separation under load. Moser Engineering's reputation for precision manufacturing ensures these studs meet the dimensional and material standards required for secure, repeatable fastening in demanding automotive applications.
