ASTM A193 B8 and B8M Stainless Steel Stud Bolts
ASTM A193 B8 / B8M specification reference for stainless steel stud bolts, threaded rods, bolts, matched nuts and industrial fastener sets where project documents specify B8 or B8M bolting materials.
ASTM A193 B8 / B8M for Project-Specified Stainless Steel Bolting
ASTM A193 B8 and ASTM A193 B8M are stainless steel bolting material specifications commonly discussed for stud bolts, threaded rods and industrial bolting assemblies where project documents specify ASTM A193 B8 or B8M.
B8 / B8M stainless steel bolting can be considered for stud bolts, threaded rods, bolts, matched nuts, washers and fastener sets where ASTM A193 B8 / B8M is specified by project requirements. Final bolting material selection should be reviewed according to service conditions and project specification. Grade, class, thread, nut pairing and certificate requirements should be confirmed before quotation.
