Metallics SW71B – Frequently Asked Questions
1) What size screw or bolt does the Metallics SW71B flat washer fit?
The SW71B is a #8 flat washer, so it pairs with #8 machine screws, sheet metal screws, and self-drilling screws. It is the washer you reach for on #8 fastener runs in panel, strut, and device-mounting work.
2) Are the Metallics SW71B washers zinc plated steel or stainless?
Zinc plated steel, not stainless. The zinc coating handles normal dry indoor electrical work, interior panel builds, and conditioned mechanical rooms. For wet, coastal, or chemically aggressive locations, specify a stainless #8 flat washer instead.
3) How is the Metallics SW71B #8 flat washer packaged, and how many come in it?
It ships as a bulk box of 28,950 #8 zinc plated steel flat washers. That is a shop or warehouse quantity, not a contractor pack, so it suits an MRO crib or a fastener bin that gets drawn down across many jobs rather than a single device trim-out.
4) Should I use a flat washer or a lock washer with #8 screws?
Two different jobs. The SW71B flat washer spreads load and protects the surface under the screw head, which is what you want through sheet metal, enclosure covers, and soft or oversized holes. A split or star lock washer resists loosening under vibration but does nothing for bearing area. On vibration-prone equipment many installers stack both, with the flat washer against the material.
5) Are Metallics SW71B washers built to an ANSI dimensional standard?
Yes, the SW71B #8 flat washer is made to ANSI dimensional standards, so the inside and outside diameters and thickness follow the published #8 flat washer sizing rather than a proprietary pattern. That matters when you are mixing washers from different lots in the same assembly.
