ARP NASCAR Speed Studs are specially designed to accurately position the wheel and to more quickly release and tighten the lug nuts. They are made from heat-treated, 190,000 psi chromoly steel and feature J-form threads, an exclusive nut starter, and a bullet-shaped radius that all but eliminates cross threading. They use a special baked-on dry film lubricant to reduce the possibility of galling and ensure consistent clamp loads and double magnaflux inspection. These products are available in a variety of lengths and knurl diameters,

Since 1968, ARP has been engineering bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels and transmissions. The company is the world leader in automotive fasteners and many top engine builders rely on ARP racing products to hold their engines together.
