Metallics JSWN12D – Frequently Asked Questions
1) What size bolt does the Metallics JSWN12D nylon flat washer fit?
The JSWN12D is a 1/2 x 3/4 nylon flat washer, so it takes a 1/2 inch bolt, rod, or stud through the 1/2 inch inside diameter with a 3/4 inch outside bearing surface. For threaded rod hanging electrical supports, that means 1/2 inch rod, not 3/8.
2) Why use a nylon washer instead of steel on an electrical install?
Nylon is non-conductive and won't corrode, so a 1/2 x 3/4 nylon flat washer is what you reach for when you need to isolate a fastener electrically or keep dissimilar metals from reacting against each other. It also spreads load without scratching a finished surface. Where you need load-bearing strength under high torque, use a steel or hardened washer instead.
3) How many washers come in a jar of Metallics JSWN12D?
Each jar holds 100 of the 1/2 x 3/4 nylon flat washers. The jar pack is handy for a van or a shop bench since it reseals and keeps the count contained rather than spilling in a bag.
4) Will a 1/2 inch nylon flat washer work under a nut on 1/2 inch threaded rod for strut and conduit hangers?
Yes. With a 1/2 inch inside diameter it slips over 1/2 inch all-thread, and the 3/4 inch outside diameter gives you a bearing face under the nut. It's a flat washer, not a lock washer, so if the assembly sees vibration add a lock nut or lock washer for retention.
5) Is the Metallics JSWN12D a single washer or a bulk pack?
It ships as a 100-piece jar of 1/2 x 3/4 nylon flat washers under part number JSWN12D, not as a loose single piece. For MRO stocking or a multi-unit job that's the quantity you're buying into.
