Metallics JBWG38 – Frequently Asked Questions
1) What is a bar joist washer used for on a 3/8 inch rod hanger?
A bar joist washer spans the open angle of a steel bar joist so a 3/8 inch threaded rod can be hung from the joist without a beam clamp or drilling. The Metallics JBWG38 is the 3/8 inch galvanized version, used for hanging conduit, strut, and pipe supports off joists on commercial electrical and mechanical work.
2) Can I use a flat washer instead of a bar joist washer on a steel joist?
No. A standard flat washer has no shape to bridge the gap between the two angles of a bar joist, so it will pull through or cock under load. The bar joist washer is formed to seat across that opening and transfer the rod load into the joist angles, which is why the JBWG38 exists as a separate part rather than as a flat washer.
3) How many Metallics JBWG38 bar joist washers come in a jar?
The JBWG38 is packed 100 pieces to a jar, so one order covers a full run of joist hangers rather than a single pick. That jar pack is how electrical contractors and MRO stockrooms buy them for the gang box or the shelf.
4) Is the JBWG38 bar joist washer galvanized for damp or unheated spaces?
Yes, the JBWG38 is galvanized, which is what you want in parking structures, warehouses, and unconditioned mechanical spaces where a plain steel washer would surface rust. For direct outdoor or corrosive duty, confirm the coating suits the environment with your spec.
5) Do I need a nut with the bar joist washer, or is it included?
The JBWG38 jar contains the washers only, 100 of them. You supply the 3/8 inch threaded rod and the hex nut that bears on top of the washer, plus whatever hanger or strut clamp lands on the bottom of the rod.
