Metallics NT31625 Anchors 3/16 (10-24) Strap-Tog Ancr St (Box 25)

The NT31625 strap toggle is sized 3/16 inch, which is a 10-24 machine screw thread. Any 10-24 machine screw will thread into it, so match your screw length to the fixture thickness plus the wall thickness.

Twenty-five strap toggle anchors per box, packed in a bag. It is a contractor pack rather than a single-piece item, so one box covers a run of fixture or device mounting rather than a one-off repair.

A strap toggle anchors into hollow walls and ceilings the same way a toggle bolt does, but the plastic straps hold the metal channel flat against the back of the board while you start the screw. That means the screw can be removed and reinstalled later without the toggle dropping into the cavity, which a conventional winged toggle bolt cannot do. For electrical work that is the difference between pulling a device or fixture off the wall for service and losing the anchor behind it.

Yes, that is the intended use. It is an electrical-department hollow wall anchor taking a 10-24 machine screw, so it suits mounting device boxes, raceway, straps, and light fixtures to drywall or hollow block where there is no stud behind. Solid concrete or brick needs a masonry anchor instead, not a toggle.
