Metallics JSSW19 – Frequently Asked Questions
1) What screw size do the Metallics JSSW19 flat washers fit?
The JSSW19 is a #12 flat washer, so it is sized for #12 machine screws and sheet metal screws. It is stainless steel, which is what you want for exterior enclosures, damp locations, or anywhere you are pairing it with stainless hardware to avoid galvanic issues.
2) How many washers come in a jar of Metallics JSSW19?
Each jar holds 100 of the #12 stainless flat washers. The jar pack is the handy-size container, not a bulk box, so it suits a service van or a shop bin rather than a production line. Total jar weight is 0.3 lbs.
3) Are stainless flat washers the right choice for outdoor electrical mounting, or should I use zinc?
Stainless is the choice when the fastener sits outside, in a wash-down area, or in a damp interior where plated zinc will bloom rust and stain the enclosure. The JSSW19 is a stainless steel #12 flat washer. Zinc-plated washers are fine for dry indoor panel work and cost less, but mixing a zinc washer with stainless screws in a wet location invites corrosion at the joint, so match the materials.
4) What does a flat washer actually do on a #12 screw in sheet metal?
It spreads the clamp load over a wider area so the screw head does not dish or pull through thin sheet, and it gives the head a clean bearing surface on slotted or oversized holes. The JSSW19 is a plain flat washer, so it does nothing to resist loosening from vibration; if the joint vibrates you want a lock washer under the nut in addition to this one.
5) Where are Metallics JSSW19 washers made?
Country of origin on the JSSW19 stainless flat washers is listed as multiple, meaning Metallics sources them from more than one country depending on the production run. If your job has a domestic-source requirement on fasteners, this is not the part to specify.
6) Will the JSSW19 jar fit in a van drawer or parts bin?
The jar measures 3 x 3 x 2.15 inches, so it drops into a standard small-parts bin or van drawer without repacking. Handy if you are standardizing a truck stock of #12 stainless hardware.
