Metallics J1212 – Frequently Asked Questions
1) What is a Metallics J1212 lag screw shield used for?
The J1212 is a lag screw shield anchor, 3/4 inch long, made of zinc-aluminum alloy. You drill a hole in masonry, concrete, brick, or block, drop the shield in, then drive a lag screw into it. The shield expands against the hole wall and holds the lag. It is the standard way to hang pipe hangers, strut, conduit straps, and brackets on solid masonry.
2) Does the J1212 lag shield come with the lag screw?
No. The jar contains the zinc-aluminum shields only. You supply the lag screws to match, and you also need a masonry bit sized for the shield body plus a hammer drill. Plan the screw length so it engages the full 3/4 inch of shield plus the thickness of whatever you are fastening.
3) Will a 3/4 inch lag shield work in hollow block or drywall?
Not in drywall, and not in the hollow cavity of a block. A lag shield needs solid material around it to expand against, so it belongs in poured concrete, brick, or the solid web of a block. For hollow wall work you want a toggle or a wall-grip style anchor instead. The 3/4 inch length also means your embedment is shallow, so keep it to light and medium duty attachments.
4) How many anchors come in a jar of Metallics J1212?
25 pieces per jar. The jar pack is the standard shop or van quantity for this anchor, so one order gets you 25 shields and nothing else; the lag screws are bought separately.
5) What part number do I order for the Metallics 3/4 inch lag screw shield?
Order Metallics J1212. That is the manufacturer part number for the 3/4 inch zinc-aluminum lag screw shield supplied in a 25 piece jar.
6) Can electricians use these to anchor conduit straps and boxes to concrete?
Yes, that is the usual job for it. The J1212 is catalogued with Metallics electrical fasteners and is used to set one-hole and two-hole conduit straps, box brackets, strut, and small enclosures onto concrete or brick with a lag screw. For heavier runs or seismic bracing, step up to a longer shield or a wedge anchor for deeper embedment than 3/4 inch gives you.
7) Is a zinc-aluminum lag shield OK for outdoor or damp locations?
Zinc-aluminum alloy gives the shield corrosion resistance beyond plain steel, which is why it is commonly used in damp interior areas and sheltered exterior masonry. For direct weather exposure or coastal work, pair it with a corrosion resistant lag screw so you are not setting up a dissimilar metal problem at the fastener.
