Wheel Stud Kit (10) 1/2-20 x 3 w/.625 Knurl

The Moser Engineering Wheel Stud Kit (10) 1/2-20 x 3 with 0.625 Knurl is a premium fastening solution engineered for custom and performance vehicle builds where reliability under high loads is non-negotiable. These 3-inch studs feature a 1/2-20 thread specification and a robust 0.625-inch knurl diameter, designed to mate precisely with custom wheels and high-performance brake assemblies. Manufactured in steel with a black oxide finish, this 10-piece kit delivers the corrosion resistance and strength demanded in serious automotive applications.

The 1/2-20 thread pitch is the industry standard for light to mid-size performance and street vehicles, offering a balance between ease of assembly and secure clamping force. The 3-inch length accommodates thicker custom wheels, spacers, and brake upgrade scenarios where stock stud length falls short. The 0.625 knurl diameter ensures consistent engagement with wheel lug nuts while resisting spinning and deformation during installation and removal—a critical detail that separates quality studs from budget alternatives. Black oxide finish provides baseline corrosion protection suitable for dry climates and garage storage, though additional protection may be warranted in salt-air or high-humidity environments.

This kit is ideal for builders upgrading to custom wheel sizes, installing wider brake components, or replacing factory studs compromised by heat cycling or corrosion. Moser Engineering's reputation in the motorsports fastening segment makes this set a reliable foundation for suspension and wheel assembly work where fastener integrity directly impacts safety and longevity. The 10-count provides a complete set for most applications, with individual spares for future maintenance or backup purposes.

Proper installation requires a torque wrench calibrated to your vehicle's specification (typically 80–130 ft-lbs depending on platform) and application of a light anti-seize compound to the threads to prevent future corrosion and seizing. Verify wheel and brake component compatibility with the 1/2-20 thread standard before ordering.
