Metallics JSSW21 – Frequently Asked Questions
1) What size flat washer is the Metallics JSSW21, and how many come in a jar?
The Metallics JSSW21 is a 1 inch flat washer in stainless steel, packed 100 to a jar. One part number, one size, so you are buying a single jar of 100 identical washers rather than an assortment.
2) Are these washers stainless steel or just zinc plated steel?
Solid stainless steel, not plated. That matters if the fasteners are going outdoors, in a damp mechanical room, on a rooftop, or anywhere a plated washer would bleed rust onto a finished surface. Pair them with stainless bolts or anchors so you are not mixing metals at the joint.
3) Is a 1 inch flat washer like the JSSW21 the right choice for spreading load on strut or sheet metal?
A flat washer is what you want for load distribution and for protecting the surface under the nut, which is exactly the 1 inch job on strut, sheet metal, or a slotted bracket where the hole is oversized. If your concern is the nut backing off under vibration, a flat washer alone will not do that work, you want a lock washer or a nylon insert nut in addition. Many crews run both: flat washer against the material, lock washer under the nut.
4) Which part number do I order for the Metallics 1 inch stainless flat washer jar?
Order Metallics JSSW21. That is the full ordering designation, there are no finish or size options to specify, and it ships as the 100 count jar.
5) Are Metallics JSSW21 washers made to ANSI dimensions?
These flat washers carry an ANSI dimensional designation, so they follow the standard inch washer sizing a 1 inch bolt or anchor is drilled and specified around rather than a metric or proprietary pattern.
