Metallics THDWH62100 Anchor 5/8 x 10 Titen HD Screw Anchor (10 pcs)

At 10 inches overall, this is a long-embedment anchor. It's meant for thick concrete sections and for fixtures with deep standoffs or thick base plates, because the fastener has to pass through the fixture before it ever reaches concrete. If you're anchoring a thin bracket flat to a slab, a shorter 5/8 Titen HD is the better match; a 10 inch anchor in that case leaves you with far more thread than the hole depth you want to drill.

A screw anchor such as the 5/8 x 10 Titen HD threads directly into a pre-drilled hole and can be removed and the hole reused or patched, which is why it gets specified where wedge or sleeve expansion anchors would be permanent. Expansion anchors still have a place when you want a one-time, high-set bolted connection, but for equipment bases, strut, standoffs, and conduit supports that may be relocated, the screw anchor is the faster install, with no setting torque sequence and no shell to expand.

Three things beyond the anchors themselves: a hammer drill with a carbide bit matched to the 5/8 inch anchor diameter, a means of clearing the dust from the hole, and an impact wrench or socket wrench to drive the hex head. The 5/8 size is past comfortable hand-driving, so plan on an impact wrench for a run of anchors. No separate nut, washer, or expansion sleeve is part of the assembly.

Order it as Metallics THDWH62100. That number covers the 5/8 by 10 inch Titen HD screw anchor in the 10 piece pack, so it's the designation to quote on a submittal or a purchase order rather than describing it by size alone.
