Metallics J1520SS Anchors Sprg Wing TogBt Rh Sl 3/8" Trd 16 Lgt 4" SS (Jar 25)

It's a 3/8 inch diameter spring wing toggle bolt with a 16 threads-per-inch (3/8-16 UNC) machine screw thread and a 4 inch overall bolt length. The head is a round head, slotted drive. 3/8-16 is the standard coarse thread pitch for 3/8 inch fasteners, so standard 3/8-16 nuts and threaded accessories will run on it.

The J1520SS is a stainless steel spring wing toggle bolt, both the bolt and the spring wing channel assembly. That's the reason to pick it over a plated carbon steel toggle: damp or corrosive locations, exterior soffits, parking structures, coastal work, wash-down areas, and anywhere a zinc-plated toggle would rust and stain the face of the panel.

No, and this is the most common mis-order on toggle bolts. A spring wing toggle only works in hollow materials, where the wings can open into a void behind the panel: drywall, plaster and lath, hollow block, hollow core doors, and sheet metal. In solid concrete, brick, or grout-filled block there is nothing for the wings to grab. Use a wedge anchor, sleeve anchor, or screw anchor for solid base material.

Twenty-five pieces per jar, and the jar is the pack unit. For an electrician hanging strut, pull boxes, or cable tray off hollow block or drywall, that's a service-truck quantity rather than a bulk box.

A spring wing toggle needs a hole large enough to pass the folded wings, not just the 3/8 inch bolt, so the drilled hole is considerably oversized compared with the screw diameter. Fold the wings flat against the channel and use that width as your minimum bit size, then push the wings through until they snap open behind the panel before tightening the slotted round head. Because the hole is oversized, the round head bears the load on the face of the material, so pair it with a washer on thin drywall or a flange fitting.

No. Once the bolt is withdrawn, the wings drop off inside the wall cavity and are gone. Plan on a fresh toggle for every remount, which is part of why the J1520SS ships 25 to a jar. If you need an anchor that stays in the wall and accepts the screw again, a hollow wall or sleeve type anchor is the right choice instead of a spring wing toggle.
