In order to provide improved clarity and consistency moving forward, the ASTM F-16 fastener committee hasastm created a new specification – ASTM F3125-15 – which consolidates six current standards under one umbrella. The six existing standards which will now fall under ASTM F3125-15 are the following –

  •          A325
  •          A325M
  •          A490
  •          A490M
  •          F1852
  •          F2280

Officially, the ASTM F3125 specification is titled “Specification 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.”

Previously, the six separate standards contained a number of minor discrepancies. With the new standard in place, there is a set guideline for all of the bolts that fall under this classification.

When comparing the previous standards with the new standard, you will find that there are only a limited number of changes to be noted. However, there are some minor adjustments that have been made, and you may wish to note those, especially if they pertain to your needs.

As for the standards that have been replaced, the A325 and A325M were specifications for steel heat-treated structural bolts. A490 and A490M applied to steel alloy heat-treated structural bolts, and F1852 and F2280 covered twist-off style bolt/nut/washer assemblies.
