Does Portland Bolt sell hot-dip galvanized bolts that meet the A153 specification?
ASTM A153 is a broad specification covering zinc coating (hot-dip) of iron and steel hardware. In the past, A153 was the hot-dip galvanizing specification referenced by ASTM construction fasteners. The problem was that ASTM Committee F16 on Fasteners did not have any jurisdiction over this specification. Therefore, in 2005 the F2329 fastener-specific hot-dip galvanizing specification was established. Both A153 and F2329 cover hot-dip galvanizing, however, Committee F16 has oversight of the F2329 specification and the ability to update or change it as they deem necessary. All common ASTM fastener specification now refer to the F2329 specification for hot-dip galvanizing. The one exception is ASTM fastener specification A193 which still references A153 for zinc plating since Committee F16 does not have oversight on this bolt grade.
