Metallics J1211 Anchors 5/8 X 3-1/2 Lag Scr Shield Zn-al (Jar 25)

No. The J1211 supplies the zinc-alloy shields only, 25 to a jar. You order the 5/8 inch lag screws separately and pick the length based on your fixture thickness plus the 3-1/2 inch shield depth.

No. A zinc-alloy lag shield is an expansion anchor for solid base material, concrete, solid brick, or solid stone. In hollow block it has nothing to expand against unless you hit the solid web, and in drywall it is the wrong anchor entirely. For hollow walls use a toggle or sleeve-type hollow wall anchor instead.

Order it as Metallics J1211. That is the manufacturer part number for the 5/8 x 3-1/2 inch zinc-alloy lag screw shield in the 25-count jar.

A lag shield like the J1211 is removable: back the 5/8 inch lag out and the fixture comes off, with the shield staying in the hole. That suits equipment you expect to service, swap, or relocate, and it lets you set the shield flush so nothing protrudes before the fixture goes on. A wedge anchor is a one-time set, permanent and generally stronger in tension, but once it is driven you are not recovering it. For serviceable mounts, the shield; for permanent structural attachment, the wedge.

The J1211 shield body is zinc-alloy, which gives it better corrosion resistance than plain steel in damp interior work and sheltered exterior use. Pair it with a galvanized or stainless 5/8 inch lag so you are not putting bare steel into the assembly. For constant wet or coastal exposure, a stainless anchor system is the safer call.

25 shields per jar. For an electrical job, that covers a run of strut, panel, or transformer mounts without reordering, and the jar keeps the loose shields together in the truck rather than scattered through a bin.
