Metallics JSSW141 – Frequently Asked Questions
1) Will the Metallics JSSW141 flat washer fit a 3/8 inch bolt?
Yes. The JSSW141 is a 3/8 inch flat washer with a 13/32 inch inside diameter, so it slips over a 3/8 bolt or threaded rod with a little clearance. Outside diameter is 13/16 inch, which is what determines how much bearing surface you get under the nut or head.
2) Are these 3/8 washers stainless steel, and can I use them outdoors or in a damp location?
The JSSW141 washers are stainless steel, which is the reason to pick them over plain or zinc plated washers on exterior strut runs, rooftop equipment, wet locations, and anywhere you are pairing them with stainless hardware to avoid rust bleed and galvanic trouble.
3) How many washers come in a jar of Metallics JSSW141?
100 washers per jar. The jar pack is the shop or truck-stock format, so one order covers a full strut or equipment-mounting job rather than a handful of fasteners.
4) What is a flat washer like this used for on an electrical install?
Metal to metal is the stated application. A 3/8 flat washer spreads the load of the nut or bolt head across the metal it is bearing on, which keeps the fastener from pulling through an oversize hole or chewing up the surface, common on strut, channel, hanger rod, and equipment mounting. It does not resist loosening from vibration, so if that is your concern you want a lock washer rather than a flat one.
5) Will these washers seat under a standard 3/8 nut, or will they stick out past it?
At 13/16 inch outside diameter, the washer extends past a standard 3/8 hex nut, which is the point. You get bearing area wider than the nut face while still clearing adjacent fasteners on tight channel spacing. If you need the washer to stay inside a narrow slot or counterbore, measure that opening against 13/16 inch first.
6) What does a jar of 100 of these 3/8 stainless washers weigh for shipping or truck stock?
0.65 lbs for the jar, in a container measuring 3 x 3 x 2.15 inches. Small enough to keep several sizes on a service van without eating shelf space.
7) What is the Metallics part number to reorder these 3/8 stainless flat washers?
Order by Metallics JSSW141. That is the manufacturer part number for the 3/8 stainless steel flat washer in the 100 count jar, and it is the only configuration under that number.
