Bolting a threaded rod to steel shapes or strut

A threaded rod is used with suspended equipment. This section includes attachment to the equipment and attachment at the top (see Suspended Attachment).

Step 1: Preparation

Determine the threaded rod size from construction drawings or printed instructions supplied by the manufacturer.

The three different ways to attach the threaded rod are shown in Figure 148

Step 2: Attach the top connection of the threaded rod

Apply washers and nuts, then tighten.

Tighten the anchor bolt to the correct torque setting shown in the manufacturer’s instructions or the construction drawings. Use a calibrated torque wrench or turn-of nut method.

Step 3: Attach threaded rods to equipment brackets

Equipment without attachment brackets requires additional steel shapes for connections to the building structure and/or roof.

Once the equipment is in place, apply washers and nuts, then tighten.

Tighten the anchor bolt to the correct torque setting shown in the manufacturer’s instructions or the construction drawings. Use a calibrated torque wrench or turn-of nut method.
