Metallics J142T Anchor 1/4 x 2 Truss Hmmr Drv Ancr St (Jar 100)

The J142T is a 1/4 x 2 inch hammer drive anchor, so it installs in a 1/4 inch hole drilled with a carbide masonry bit. Drill the hole deeper than the embedment you need so drill dust has somewhere to go, set the fixture over the hole, push the anchor through, and drive the pin flush with a hammer. The 2 inch length is the overall anchor length, so your fixture thickness comes off the available embedment in the concrete or block.

Drive anchors like the J142T need a solid base material. They expand against the sides of the hole, so they hold in poured concrete, brick, and the solid webs of block. In a hollow block cell or in drywall there is nothing for the body to grip, and the anchor will spin or pull straight out. For hollow walls use a toggle or hollow wall anchor instead.

No. A drive pin anchor is a permanent fastener, and the J142T is no exception. Once the pin is driven, the body expands in the hole and there is no reliable way to back it out or reuse it. If you need the connection to come apart later, use a removable anchor such as a sleeve or wedge type with a threaded nut, or a screw anchor, instead of a drive pin.

100 pieces per jar. For bidding purposes, count one anchor per strap hole or clip and add overage for anchors you lose to blown-out holes or rebar strikes, which are common in older slabs.
