Roll-Fast is a manufacturer of Stud bolts for Ship Engines & Automotives from M10 to M100 or 1/2” to 4” diameters. The all-thread stud bolt is a threaded rod with 2 heavy hex nuts, while the tap end and double end are nut continuously threaded, but have a body in the middle with one nut. The Stud Bolts provide the ability to obtain much more accurate torque values because the studs don't twist during tightening as do bolts In a tap end the short end of the stud bolt is designed with a UNC 3A fit to go into a tapped hole on the body of a larger machined or forged equipment. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurat...

Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces. the Stud Bolt is the same as a normal bolt but without any head. The stud bolt can be full thread or half / partial thread on both sides.
