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.
