1/2" x 2" Socket Shoulder Bolts
ASTM A320 B8. Machined to the customer's drawing in our Houston shop.
1/2" x 2" (3/8-16 UNC-3A x 0.625") Socket Shoulder Bolts, manufactured to ASTM A320 B8 standards delivering unmatched precision, strength, and reliability in critical applications.
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: 304 stainless bolting certified to the low-temperature specification — the same 75 ksi solution-treated material as A193 B8, with A320 impact rules and matching A194 Grade 8 nuts. Read the A320 B8 Class 1 data page →
