Metallics NT3815J – Frequently Asked Questions
1) What thread size bolt does the Metallics NT3815J strap toggle anchor take?
The NT3815J strap toggle is sized for 3/8-16 threaded bolts or rod, so whatever you hang off it has to be 3/8 inch diameter with 16 threads per inch (standard UNC coarse). It will not accept 1/4-20 or 1/2-13 hardware.
2) How many anchors come in a jar of Metallics NT3815J?
Fifteen strap toggle anchors per jar. The jar pack is the only way the NT3815J is put up, so order by the jar rather than by the piece.
3) Are the NT3815J toggle anchors corrosion protected?
They are zinc plated steel. That is fine for dry interior work, hollow block, drywall and ceiling hangers inside a conditioned building. For wet, exterior or corrosive locations you want a stainless anchor instead, since zinc plating is a sacrificial coating, not a stainless base metal.
4) What is a strap toggle and when should I use one instead of a standard spring-wing toggle bolt?
A strap toggle uses plastic straps to pull a steel channel bar flat against the back face of a hollow wall or ceiling, then the straps snap off at the surface. The advantage over a spring-wing toggle is that the bar stays in place when you back the bolt out, so you can remove and reinstall the fixture without losing the anchor into the cavity. Use a spring-wing toggle only where you never plan to take the bolt out again.
5) Can I use the Metallics NT3815J to hang threaded rod for conduit or strut from a hollow deck?
Yes, that is the usual electrical application. The NT3815J takes 3/8-16, which is the common rod size for trapeze hangers, strut and conduit support, and it is a hollow-wall and hollow-base-material anchor rather than a solid concrete anchor. Match the load to whatever your engineer or the AHJ requires for the base material you are anchoring into.
6) What is the exact part number to order these 3/8-16 strap toggles?
Metallics part number NT3815J. The N-T prefix covers the strap toggle line, 38 is the 3/8 inch thread, 15 is the fifteen-piece count and J denotes the jar put-up.
