Metallics J1567 Anchors Sprg Wing TogBt 1/4" Trd 4" (Jar 50)

The Metallics J1567 is a spring wing toggle bolt with a 1/4 inch diameter thread and a 4 inch bolt length. The 4 inch length is what gives you enough shank to pass through the fixture, through the wall board or block, and still let the spring wings snap open and draw up tight behind it.

Yes, that is the job a spring wing toggle is for. It anchors into hollow materials, drywall, hollow block, hollow tile, where there is open cavity behind the face and no solid base for a screw anchor. The J1567 is catalogued as electrical supply fastening stock, the kind used for conduit straps, box mounting, and strut or fixture support in hollow walls and ceilings.

No. A spring wing toggle like the J1567 needs open cavity behind the wall so the wings can spring apart and bear on the back face. In solid concrete, brick, or grout-filled block there is nothing for the wings to open into. For solid base material use a sleeve anchor, wedge anchor, or a screw anchor rated for masonry instead.

Fifty pieces, packed in a jar. That is a quantity sized for a crew doing repeat hollow-wall or hollow-block anchoring, so a maintenance shop or electrical contractor can keep one container on the truck instead of loose bagged singles.

The hole has to be large enough to pass the folded wings through, so it is noticeably bigger than the 1/4 inch bolt itself, not a close fit to the thread. And once the bolt is backed all the way out, the wing assembly drops into the cavity and is gone, so plan on a new toggle rather than reusing the hole hardware if you ever pull the fixture.
