Metallics J3161T Anchor 3/16 x 1 Truss Hmmr Drv Ancr S (Jar 100)

The J3161T is a 3/16 x 1 inch hammer drive anchor, so it sets in a 3/16 inch hole drilled with a masonry bit. Drill the hole deeper than the 1 inch anchor length so drill dust has somewhere to go, set the fixture over the hole, then drive the pin home with a hammer. No expansion tool or torque wrench needed.

Yes, that is the usual job for it. The truss head on the J3161T is wide and low profile, so it covers the oversized slot in a one hole strap or clip without pulling through, and it sits flat enough that it won't interfere with the conduit. For anything you expect to remove and reinstall, use a screw anchor instead, since a driven pin anchor is permanent.

No. A hammer drive anchor needs solid base material, concrete, solid masonry, or brick, because it holds by the pin expanding the body against the sides of the hole. In drywall or an empty block cell there is nothing to expand against, so it will spin or pull straight out. Use a toggle or self drilling drywall anchor for hollow substrates.

They ship 100 per jar. That is a single bulk container of the 3/16 x 1 inch truss head drive anchor, which suits an electrician stocking a van or a shop keeping one size on the bench for repetitive strap and box work.

Order it as Metallics J3161T. That number covers the 3/16 x 1 inch truss head hammer drive anchor supplied 100 to a jar, and it is the only model on the item, so there is no finish or length option to pick.
