In 2016, ASTM A325 was officially withdrawn and replaced by ASTM F3125, in which A325 now becomes a grade under the F3125 specification.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.

    How to Install a Steelcraft Bull Bar
    Video Transcript:

    Hello. Shawn here, with RealTruck. Today, we’re going to be installing a Steelcraft bull bar in a ’04 Chevy Silverado.

    Here’s a bull bar with all the included hardware.

    First, you’ll need to take off the factory tow hooks on both the driver and passenger sides.

    Next, put the included bolt into existing hole on frame, and through the mount. Add nut, and slightly tighten. Now put the front bolt into the frame, and through the bull bar mounting bracket. Add nut, and slightly tighten. Repeat the exact same process on both driver and passenger sides.

    Now it’s time to apply the bull bar. Use a buddy’s assistance, if possible. Line holes up with the bull bar mount. Add bolts, and tighten slightly. Repeat the same process on the other side.

    Now that the bull bar is completely installed, it’s time to tighten all the bolts. You can do this with a regular socket wrench. Or as you can see, an air wrench works pretty good, as well.

    Here’s the finished product for a more rugged appearance.
