Metallics JHW58434 Anchors 5/8 x 4-3/4 Hmmr Drv Wdg Zn-C (Jar 25)

Drill 5/8 inch. The JHW58434 is a 5/8 x 4-3/4 inch hammer drive wedge anchor, and wedge anchors use a hole the same nominal diameter as the anchor, drilled deeper than the embedment so debris has somewhere to go. Clean the hole out, then drive the anchor through the fixture with a hammer and tighten the nut to set the wedge.

Wedge anchors like the JHW58434 are designed for solid, poured concrete. They work by expanding a wedge against the wall of the drilled hole, so hollow block, brick, mortar joints, and grout do not give them the compressive strength they need. For hollow masonry, use a sleeve anchor or a toggle rated for the base material instead.

Twenty-five anchors per jar, and the jar is the pack unit the 5/8 x 4-3/4 size ships in. For a conduit rack or strut run, count your hole positions first, a single jar covers 25 holes.

The JHW58434 is zinc plated carbon steel, which is an indoor or dry location finish. Plated zinc will corrode in weather, wash-down areas, or anywhere exposed to chlorides. For exterior slabs, parking structures, or mechanical yards, specify a hot dip galvanized or stainless wedge anchor instead.

The 4-3/4 inch overall length has to cover your embedment plus the thickness of whatever you are fastening plus the nut and washer. Subtract the embedment depth you need in the concrete from 4-3/4 inches and what remains is your usable grip. If you are stacking a thick base plate or shimming, step up to a longer 5/8 anchor rather than shorting the embedment.

No. A hammer drive wedge anchor of this type comes assembled with its nut and washer on the threaded end, which is what you hammer on to drive it and then turn to expand the clip. Nothing else is supplied, you provide the hammer drill, the 5/8 inch carbide bit, and a wrench to torque the nut.

It is the standard through-fixture anchor for bolting heavy gear to a concrete slab or wall, transformer and panel frames, strut and trapeze hangers, cable tray supports, unistrut uprights. At 5/8 x 4-3/4 inches the JHW58434 is on the heavy end of that range, suited to equipment anchorage rather than light conduit clips. Metallics catalogues it with its electrical fastener line.
