Metallics JSWBR12 – Frequently Asked Questions
1) Will the Metallics JSWBR12 brass flat washer fit a 1/2 inch bolt?
Yes. The JSWBR12 is a 1/2 inch flat washer with a 17/32 inch inside diameter, so it slips over a 1/2 inch bolt or threaded rod with normal clearance rather than binding on the threads.
2) Are these washers solid brass or just brass plated?
Solid brass. The material on the JSWBR12 flat washer is listed as brass, which is why electricians reach for it on grounding and bonding connections where a non-ferrous, corrosion resistant washer is wanted instead of plated steel.
3) Should I use a flat washer or a lock washer with a 1/2 inch bolt?
Two different jobs. The JSWBR12 is a flat washer, so it distributes clamping load across the surface and keeps the nut from chewing into the material. It does nothing to resist loosening from vibration. On a vibrating assembly, use a flat washer against the surface and add a split-ring or tooth lock washer under the nut.
4) Do the Metallics brass washers meet ANSI dimensional sizing?
ANSI is the dimensional standard listed for the JSWBR12, so the 1/2 inch size follows standard washer sizing and will interchange with other ANSI dimensioned 1/2 inch flat washers already on the job.
