Metallics JHAB11 – Frequently Asked Questions
1) What thread size and length are the Metallics JHAB11 hanger bolts?
The Metallics JHAB11 hanger bolt is 3/8-16 by 3 inches overall. One end is a 3/8-16 machine thread for threaded rod couplings, strut nuts, or hanger nuts; the other end is a wood screw thread that drives into a joist or wood blocking. Steel with zinc plating.
2) Can I hang 3/8 inch threaded rod from the JHAB11 hanger bolt?
Yes. The machine-thread end is 3/8-16, the same thread as standard 3/8 inch all-thread rod, so a 3/8-16 coupling nut ties the rod directly to the bolt. That is the usual way to drop conduit hangers, strut, or fixture supports off a wood joist.
3) How many hanger bolts come in the Metallics JHAB11 package?
100 bolts, packed in a jar. The jar packaging suits a service van or a shop shelf where you are pulling a few at a time rather than opening a bulk carton.
4) Will a 3 inch hanger bolt hold in a 2x wood joist?
At 3 inches overall, only part of that length is the wood screw end, so the embedment into a nominal 2x joist (1-1/2 inches actual) will be shallow if you leave much machine thread exposed. Drive it into solid framing or blocking, not sheathing or furring, and pre-drill a pilot for the lag end so the zinc-plated steel threads pull in clean rather than splitting the wood.
5) Is a zinc-plated hanger bolt okay for outdoor or damp locations?
The JHAB11 is zinc-plated steel, which is a dry-interior finish. For exterior, wet, or corrosive locations use a hot-dip galvanized or stainless hanger bolt instead; plain zinc will rust through where it gets wet.
6) What is the difference between a hanger bolt and a lag screw for overhead electrical supports?
A lag screw has a head you drive with a wrench and nothing left to attach to once it is set. A hanger bolt like the JHAB11 has no head at all: wood thread on one end, 3/8-16 machine thread on the other, so it leaves a stud sticking out of the joist that you can nut, couple, or run rod off. Use the hanger bolt when something has to hang below the wood; use a lag when you are clamping a bracket flat to it.
7) How do you install a headless hanger bolt without a wrench flat?
Thread two 3/8-16 nuts onto the machine end and jam them against each other, then turn the top nut with a wrench to drive the wood end into a pilot hole. Back the nuts off once it is seated. There is no head on the JHAB11 to grip, so the double-nut method, or a hanger bolt driver in a 3/8-16 size, is how it goes in.
