Metallics JHW584 Anchors 5/8 X 4 Hmmr Drv Wedge Ancr St (Jar 25)

A wedge anchor is drilled to match its own nominal diameter, so the Metallics JHW584 goes into a 5/8 inch hole drilled with a carbide hammer bit. Drill the hole deeper than the intended embedment so cuttings have somewhere to go, blow it clean, then drive the anchor through the fixture into the concrete.

Not reliably. At 4 inches overall, the JHW584 needs most of that length embedded in sound concrete plus clearance below the anchor for the slab to hold, so it belongs in thick slabs, footings, or structural walls. For a 4 inch topping slab or a hollow block wall, step down to a shorter anchor or switch to a sleeve or toggle type fastener suited to the base material.

25 anchors per jar. The jar pack is the standard put-up for the 5/8 x 4 inch hammer drive wedge anchor, which suits a job where you are setting a run of equipment bases or strut supports rather than a single hole.

A wedge anchor like the 5/8 x 4 inch JHW584 is a solid steel stud with an expansion clip at the base, it only works in solid poured concrete and gives the higher holding value, which is why it is specified for structural and equipment anchoring. A sleeve anchor expands along a longer body and is the one to use in block, brick, or softer masonry where a wedge would spall the hole.
