These custom grade 8 T-bolts were produced using SAE J429 material to Grade 8 specifications, finished with a black oxide process. An existing sample was used to recreate the design and tooling for the head shape. 3/8-20 unorthodox thread pitch was rolled at thread length of .8" minimum. Overall length of the part was set at 1.212" +/-.01" and the max head diameter reached .757" +/-.01". Full certs were provided with the parts.
