Which is the new ASTM specification for structural bolts?
Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in May 2016 and replaced by Specification F3125/F3125M for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions.See all results for this questionWhat are the dimensions of ASTM A325 hex bolts?ASTM F3125: Standard Specification for High Strength Structural Bolts and Assemblies, Steel and Alloy Steel, Heat Treated, Inch Dimensions 120 ksi and 150 ksi Minimum Tensile Strength The ASTM A325 specification covers high strength heavy hex structural bolts from ½ diameter through 1-1/2 diameter.See all results for this questionWelding of Gr. 5 and/or A325 Bolt - Welding, Bonding astm a 325n bolts welding bonding fastener Heat treatmentMay 31, 2006 · Aug 30, 2006 · The ASTM A325 bolt is quenched and tempered. Welding it will produce untempered martensite in the heat affected zone. If the weld is around the head of the bolt, the heat affected zone may extend to the shank of the bolt and result in a brittleness just where you don't want it, i.e., under the head of the bolt.

Can a A563 nut be welded to a A325 bolt?
Everyone involved realizes that A325 bolts and A563 nuts are not supposed to be welded, and A325 bolts are not on the D1.1 list of approved base metals, and most likely the connections will be reviewed to be welded. However, the question came up and it deserves an answer but I haven't found a direct reference that answers it.Reference: app.aws.org/forum/topic_show.pl?tid=12078See all results for this questionASTM A325 hex bolts,ASTM F3125 Grade A325 / A490 Type Specification ASTM A325 for High Strength Structural Bolts was withdrawn in May 2016, and replaced by ASTM F3125.
