1-1/2"-6 UNC-2A x 3-1/2" Flat Head Socket Cap Screw, fully threaded per B18.3, is built for demanding performance, every time.
Special socket products are machined from bar where the specification allows, with the socket broached and the threads rolled, or cut where the specification or order allows, then heat treated and plated as the specification requires. Shoulder, low-head, flat-head and set-screw patterns follow ASME B18.3 unless the drawing says otherwise.
About the material: Nitronic 50 bolting — twice the yield strength of 316 with better seawater corrosion resistance and no loss of ductility, non-magnetic even after cold work. Read the A193 B8R data page →
