Metallics J1534 Anchors Sprg Wing TogBt 3/16" #10 5" (Jar 50)

That is the normal use for a spring wing toggle like the J1534. The wings compress to pass through a drilled hole, then spring open behind the drywall, lath, plaster, or hollow block and spread the load across the back face. Because the wings have to open inside the cavity, you need open space behind the hole, and the 5 inch bolt means the wings can travel past a thick build-up (double layer board, a plaster coat, a furred ceiling) before they set. It is not an anchor for solid concrete or brick, where you want a sleeve or wedge anchor instead.

A 3/16 inch spring wing toggle takes roughly a 5/8 inch hole, because the folded wings, not the bolt, set the hole size. Drill it in the ceiling or wall board first, thread the fixture or strap onto the bolt before you insert it, then push the folded wings through and pull back on the bolt while you tighten. If you take the nut off after it is set, the wing drops into the cavity and is gone, so plan the order of assembly.

For anything carrying real weight off a hollow wall or ceiling, a steel spring wing toggle like the 3/16 inch J1534 is the right call: the wing bears against the back of the board over a wide area instead of relying on the board's crumbly core the way a plastic expansion anchor does. Plastic anchors suit light items such as a cover plate or a small bracket. Where the cavity is too shallow for the wings to open, or the base material is solid, a toggle is not the answer at all.

Spring wing toggle bolts ship as a complete unit, machine screw plus the spring-loaded wing threaded onto it, so a jar of 50 J1534 gives you 50 ready-to-install assemblies in the 3/16 inch, 5 inch size. Nothing else is required beyond a drill bit sized for the folded wing.

It comes as a jar of 50 toggle bolts, which is how electrical and MRO buyers usually stock them, one container per gang box or van drawer rather than loose counts. Each jar is a single part number, J1534.
