Metallics J1593SS Anchors 1/4-20 S-Wing Tog Hd SS (Jar 50)

The J1593SS spring wing toggle anchors are 1/4-20, so they take a standard 1/4-20 machine thread. That matters when you are pairing them with strut, boxes, or hanger hardware already tapped or drilled for quarter-inch fasteners.

Yes, the J1593SS is the stainless steel version of the spring wing toggle. That is the one to use where the fastener sees moisture or washdown, such as exterior soffits, parking structures, or damp mechanical rooms, where a plain zinc toggle would rust out at the head.

A spring wing toggle is a hollow-wall anchor. The wings fold flat to pass through a drilled hole in drywall, plaster, hollow block, or a metal deck, then spring open behind the wall and clamp as you tighten the bolt. Electricians use them to hang boxes, fixtures, raceway straps, and small enclosures where there is no stud or solid backing. If you have solid concrete or a stud behind the surface, use a concrete anchor or a wood screw instead, since a toggle needs open cavity space to expand.

Yes. With any spring wing toggle, the bolt length has to cover the wall thickness plus whatever you are fastening through, with enough thread left for the wings to seat and draw tight. Measure the finished wall and the stack of material at the mounting point, then confirm the bolt length before you drill. Also confirm there is clear cavity space behind the hole for the wings to open, since they cannot deploy against insulation batts packed tight or a solid back-up.

No. Once you back the bolt out of a spring wing toggle, the wings drop into the wall cavity and are gone. Plan on a fresh anchor for any remount, which is one reason these are sold fifty to a jar rather than in small counts.
