Metallics J141R – Frequently Asked Questions
1) What size is the Metallics J141R hammer drive anchor and how many come in a jar?
The J141R is a 1/4 x 1 inch round head hammer drive anchor in zinc plated steel, packed 100 per jar. The 1/4 refers to the anchor diameter and the 1 inch is the anchor length, so it suits thin fixtures over masonry or concrete where you only need about an inch of embedment.
2) How do you install a 1/4 inch hammer drive anchor like the Metallics J141R?
Drill a 1/4 inch hole through the fixture into the masonry or concrete, hole depth at least the anchor length, blow the dust out, push the anchor through the fixture hole and drive the pin flush with a hammer. Driving the pin expands the body of the anchor in the hole. There is no nut or torque setting, which is why electricians use these for pipe straps, clips and small boxes on block or concrete. They are a permanent fastener, not meant to be backed out and reused.
3) Will a 1/4 x 1 inch drive anchor hold in hollow block or drywall?
No. A hammer drive anchor of this type expands against solid material, so it belongs in poured concrete, solid brick or the solid web of block. In a hollow block cell or in drywall there is nothing for the body to grip and it will spin or pull out. For hollow walls use a toggle or a sleeve type hollow wall anchor instead.
4) Is the Metallics J141R anchor suitable for outdoor or damp locations?
The J141R body is zinc plated steel. Zinc plating gives ordinary indoor corrosion protection and tolerates occasional dampness, but it is not stainless. For continuous exterior exposure, coastal air, or wet and chemical environments, specify a stainless anchor rather than zinc plated carbon steel.
5) Should I use a hammer drive anchor or a Tapcon style screw anchor for mounting conduit straps to concrete?
A drive anchor like the 1/4 x 1 J141R is faster where the fastening is permanent: one hole, one hammer blow, no driver needed, and 100 to a jar for repetitive strap or clip work. A concrete screw is the better choice when the fixture may be removed or re-shimmed later, since the screw backs out. Drive anchors are not meant to be removed and reused.
6) What does the round head on the Metallics J141R anchor mean for the finished look?
RH is a round head, so the J141R seats with a low domed head on top of whatever you are fastening. That head bears directly on the strap or clip and spreads the load, so no washer is needed. If you need the head to sit flush in a countersunk hole, a round head drive anchor is the wrong profile.
