Metallics J1593 Anchors 1/4-20 S-Wing Tog Hd St-zn (Jar 100)

It is the spring wing toggle head only, in 1/4-20, not a head-plus-screw assembly. You supply the 1/4-20 machine screw at the length your fixture and wall thickness require. Buyers restocking a van usually keep a jar of heads and a range of screw lengths rather than fixed-length kits.

A 1/4-20 machine screw. The J1593 toggle head is tapped 1/4-20, so any standard 1/4-20 screw threads into it; pick the length so the wings clear the back face of the hollow wall and still let the screw draw the fixture tight.

Steel with zinc plating. That suits dry interior work, hollow block, drywall and plaster ceilings inside conditioned space. For wet, exterior, or corrosive locations, specify a stainless anchor instead rather than relying on the zinc coating.

Hanging into hollow walls and hollow ceilings where there is no stud or solid backing: strut, box supports, raceway, light fixtures, cable tray hangers. The spring wings fold to pass through the hole, then snap open behind the wall and spread the load across the back face. The J1593 head takes a 1/4-20 screw, the common size for threaded-rod and fixture support hardware.

No. Toggle heads need an open cavity behind the material so the wings can spring out. In solid concrete, brick, or grouted block, use a concrete anchor such as a wedge anchor, sleeve anchor, or screw anchor sized for the 1/4 inch hardware instead.

100 heads per jar. The jar pack is what an electrical contractor or MRO stockroom wants for repeat hollow-wall and hollow-block hanging work, since it keeps loose heads together on the shelf instead of in bags.

No. Once the screw backs out, the wing head drops into the wall cavity and is gone. Order enough heads to cover rework, which is part of why the J1593 is sold 100 to a jar.
