5/8" x 1-1/2" socket head shoulder screws in ASTM A193 Grade B16, ready to ship 24 hours after the customer called.
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: Vanadium-strengthened Cr-Mo bolting that holds its strength where B7 starts to relax — steam turbines, HP steam flanges and hot valve bonnets. Read the A193 B16 data page →
