In 2016, ASTM A325 was officially withdrawn and replaced by ASTM F3125, in which A325 now becomes a grade under the F3125 specification. The F3125 specification is a consolidation and replacement of six ASTM standards, including; A325, A325M, A490, A490M, F1852, and F2280.
Prior to its withdrawl in 2016, the ASTM A325 specification covered high strength heavy hex structural bolts from 1/2″ diameter through 1-1/2″ diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.
This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A449.
Bolts for general applications, including anchor bolts, are covered by Specification A449. Also refer to Specification A449 for quenched and tempered steel bolts and studs with diameters greater than 1-1/2″ but with similar mechanical properties.

Are you an electrician looking to find out how to avoid pre-drilling holes in metal? If you are, you’ll love this video on how quick and easy Orbix self-drilling screws are to use when compared to traditional nuts and bolts.
The video demonstrates how long it takes to attach a metal sheet to a fixed metal plate using Orbix screws compared to standard nuts and bolts. Without the need to mark out and pre-drill holes in the metal when using Orbix screws, the time it takes for the Orbix installation (the one on the right) is considerably less than the standard installation (the one on the right).
Orbix self-drilling screws drill, fix and tighten in one simple operation using a standard Pozi No2 drive bit in your cordless drill. This makes the installation process considerably quicker, and with no fiddly nuts and bolts or spanners or screwdrivers to use, much easier too.
Trials have proved that each box of Orbix screws could save over two hours on installation time, making electrical installations quicker, easier and more cost-effective than ever before.
