Metallics JSW72D – Frequently Asked Questions
1) Are the Metallics #10 flat washers zinc plated for corrosion resistance?
Material is zinc plated steel. That handles dry indoor and protected panel work (device boxes, enclosure covers, strut and channel mounting). For wet exterior or coastal exposure, go stainless instead, since zinc plating wears through once it is scratched or sits in standing water.
2) Is a flat washer or a lock washer the right choice for electrical device mounting?
Two different jobs. A flat washer like the JSW72D spreads the load and protects the surface under the screw head, which is what you want on sheet metal covers, enclosure doors, and plated panels where the head would otherwise dig in or pull through. A split or internal-tooth lock washer resists loosening from vibration but does nothing to distribute pressure. On equipment that vibrates, many installers stack both: lock washer against the head, flat washer against the material.
3) Are these Metallics washers made in the USA?
Country of origin is the United States, which matters if you are filling a government, school district, or federally funded job with domestic sourcing language in the spec. The washers are also built to ANSI dimensional standards.
4) Can I use #10 flat washers under grounding screws and bonding lugs?
Zinc plated steel flat washers are fine as a load-spreading washer under a #10 grounding or bonding screw head, keeping the screw from cutting into a thin box or bracket. They are not a substitute for a listed grounding washer or a star washer where the bond has to bite through paint, and the plating itself is not what carries the bond.
5) What part number do I order for Metallics #10 zinc flat washers by the jar?
Order Metallics JSW72D. That is the single part number for the #10 flat zinc plated steel washer in the 100-count jar; there are no size or finish options to pick under it.
