Metallics JSW74G – Frequently Asked Questions
1) Are these 5/16 flat washers OK for outdoor or damp electrical installs?
Galvanized steel is what the JSW74G is made of, and the zinc coating is the usual choice for exterior strut, conduit support, and damp indoor locations where plain steel would rust. For continuously wet, coastal, or chemically aggressive settings, stainless is the better call. The finish gives the washer a grey appearance.
2) How many washers come in a jar of Metallics JSW74G?
Each jar holds 100 of the 5/16 inch galvanized flat washers, and the filled jar weighs 1.13 lbs. The jar packaging is the practical part for a van or a gang box: it keeps loose washers from scattering across a tray the way a poly bag does, and it reseals between jobs.
3) What is a flat washer actually doing under the nut, and do I need one on both sides?
A flat washer like the 5/16 inch JSW74G spreads the clamp load over a wider area than the nut or bolt head alone, which keeps the fastener from pulling through or crushing softer material, and it gives the nut a clean bearing surface to turn against. On wood, sheet metal, or any oversized or slotted hole, use one under the nut and one under the head. On a tapped hole or a strut channel nut, one under the head of the bolt is normally enough. Note that a flat washer does not resist loosening from vibration; that is what a split lock washer is for.
4) What part number do I order for Metallics 5/16 galvanized flat washers?
Order Metallics JSW74G. That is the manufacturer part number for the 5/16 inch galvanized steel flat washer supplied in a 100-piece jar, and it is the single configuration offered under that number.
