Metallics JRWV37100 Thread Rod 1/4 X 1 Wood V-Mt Ancr St-zn (Jar 25)

It's a 1/4 x 1 inch V-mount wood anchor in steel zinc that gives you a 1/4 inch threaded rod take-off point in a wood member. You drive it into the wood joist or stud, then thread 1/4 inch rod into it to hang conduit, strut, or pipe. It's the wood equivalent of a drop-in anchor in concrete, so electrical and mechanical trades use it where the overhead framing is lumber rather than deck.

1/4 inch rod, 1/4-20 being the standard thread for that diameter. The anchor's 1 inch dimension is the body length driven into the wood, not the rod length, so you order your rod separately in whatever drop you need.

No. It's a wood anchor, meant for lumber framing only. For concrete you need a drop-in or wedge anchor rated for 1/4 inch rod; for bar joist or steel deck you'd use a beam clamp or rod hanger instead.

25 anchors per jar, and the jar is the pack form. That's a practical count for a single rough-in run rather than a bulk box, so stock multiples if you're hanging a long conduit route or trapeze line.

Yes. The jar covers the anchors only. You still need 1/4 inch threaded rod cut to your drop, plus the hanger itself (conduit clamp, strut, or pipe hanger) and the nuts and washers to secure it to the rod.

The anchor is steel with a zinc finish, which handles normal interior and dry-to-damp conditions. For exterior or wet, corrosive environments, specify stainless or hot-dip galvanized hardware instead.
