Metallics JSW77 – Frequently Asked Questions
1) Will the Metallics JSW77 flat washer fit a 5/8 inch bolt?
Yes. The JSW77 is a 5/8 inch flat washer with a 21/32 inch inside diameter, so it slips over a 5/8 inch bolt or threaded rod with just enough clearance to seat without binding.
2) Are these Metallics 5/8 washers plated for corrosion resistance?
The JSW77 washers are steel with a zinc finish, listed as zinc chromate. That handles normal indoor and protected electrical work, panel and strut mounting, and general metal to metal fastening. For continuous outdoor exposure or wet, corrosive environments, a stainless washer is the better choice.
3) How many washers come in a jar of Metallics JSW77?
Each jar holds 100 of the 5/8 inch flat washers, packed in a jar rather than a loose bag, which keeps them contained on a van shelf or a gang box. Total packed weight is 2.6 lbs.
4) What is a flat washer like the JSW77 used for versus a lock washer?
A flat washer spreads the load of the nut or bolt head over a wider area of the mating surface, which keeps the fastener from pulling through or deforming sheet metal and strut. It does nothing to resist loosening from vibration. If the joint vibrates, add a split or tooth lock washer under the nut and keep the flat washer against the workpiece. The JSW77 is rated for metal to metal work.
5) Can I use these 5/8 flat washers with 5/8 threaded rod for hanging electrical and HVAC supports?
Yes, for the nut side of a 5/8 inch rod hanger the 21/32 inch inside diameter clears the rod and the flat face bears on the channel or fitting. Note these are standard-pattern flat washers, not the thicker, wider fender or structural washers some seismic bracing details call out, so check the detail if the drawing specifies a particular washer series.
