Stud bolts and related fasteners — where to start

Most flange enquiries come down to three questions: which ASTM grade (B7, B8, L7…), what diameter × length, and whether a coating is required. This page is our map of stud bolts, nuts and washers.

  • ASTM A193 — B7 / B7M / B16 alloy, B8 / B8M stainless class 1 & 2
