Features

Unbrako Socket Head Shoulder Screws are hardened shafts with a knurled head and threaded portion. The shoulder formed where the threads meet the larger diameter body acting as a stop when the screw is threaded into a tapped hole, permitting the screw to be used as a pivot, shaft, or stationary guide. The precision tolerance on the shoulder provides close and accurate mating with the fastened components. Unbrako manufactures to a tolerance position closer than that required by international standards.

  • Precision hex socket provides maximum wrenching strength and full tightening without cracking or reaming socket, along with ample metal in fillet area for maximum head strength.
  • Controlled concentricity between head and body for easier, more accurate assembly
