ASTM Consolidates Structural Fastener Specifications

The ASTM Committee F16 on Fasteners has consolidated six structural fastener standards into ASTM F3125. The new standard covers structural fasteners for holding steel structures together from high-rise construction to retail to airport terminals to sports facilities.

ASTM touted the new “streamlined approach” with one standard: F3125 Specification for High Strength Structural Bolts, Steel & Alloy Steel, Heat Treated, 120 ski (830 MPa) and 150 ski (1040MPa) Minimum Tensile Strength, Inch and Metric Dimensions.

“This is an example of what can happen when fresh perspectives, cooperation and effort combine,” said subcommittee chair Chad Larson of LeJeune Bolt Co. “The new standard maintains virtually all of the previous technical requirements and ads much needed changes in a very efficient manner.”

The six standards consolidated into ASTM F3125 are: ASTM A325 and A325M for steel heat-treated structural bolts; ASTM A490 and A490M for steel alloy heat-treated structural bolts; and ASTM F1852 and F2280 for “twist off” type tension control structural bolt/nut/washer assemblies.

The F16 committee worked with the American Institute of Steel Construction and Research Council on Structural Connections.

With hundreds of millions of fasteners manufactured to ASTM specifications annually, fastener manufacturers, structural engineers and steel construction agencies will benefit from the streamlined standard, according to ASTM.
