They’re made from heat-treated 190,000 psi chrome moly steel and feature precision J-form threads (formed after heat-treat for improved fatigue strength), exclusive nut-starter and bullet shape radius that all but eliminates cross-threading, shot-peening, special baked-on dry film lubricant (reduces possibility of galling and assures consistent clamp loads), and double magnaflux inspection. The head design fits the registers of all popular hubs without grinding, and studs are available in 31 underhead lengths to provide you with the optimum thread engagement for your particular setup. The finest studs available! Speed Studs™ NOTE: All Speed Stud™ applications fit Stock Car Products and Speedway Engineering Hubs without grinding or modifications.
