Metallics JSW73M – Frequently Asked Questions
1) Are Metallics JSW73M washers zinc plated steel or stainless?
Steel with a zinc plating, silver in appearance. Zinc plated steel is the normal choice for dry interior electrical work, strut, and box mounting. For wet locations, coastal exposure, or anywhere chlorides are present, stainless is the better call, since zinc plating is a sacrificial coating rather than a corrosion resistant base metal.
2) How are the Metallics JSW73M 1/4 inch washers packaged for a service van?
They come 1000 pieces in a jar, which is the shop or van stock pack rather than a small blister card. The filled jar weighs 4.62 lbs and measures 3.5 x 3.5 x 5.75 inches, so it sits in a standard van shelf bin or on a parts rack without repacking.
3) Do I need a flat washer or a lock washer for mounting electrical boxes and strut?
They do different jobs and are often used together. The JSW73M is a flat washer: it spreads the clamping load of the nut or bolt head over a wider area so the fastener does not dig into sheet metal, plywood, or a box knockout. A lock washer resists loosening under vibration. On a vibrating assembly the usual stack is flat washer against the material, lock washer under the nut.
