Metallics SW70B – Frequently Asked Questions
1) Are Metallics SW70B washers steel or stainless, and will they hold up in a damp location?
These are zinc plated steel, not stainless. The zinc gives ordinary indoor and protected corrosion resistance, which is fine for panel work, box and device mounting, and dry or damp interior locations. For direct wet exposure, coastal air, or anywhere chemically aggressive, specify stainless instead.
2) Should I use a flat washer or a lock washer with #6 screws?
A flat washer like the SW70B spreads the load and protects the surface under the screw head, which is what you want against sheet metal, enclosure walls, or soft material where the head would otherwise dig in or pull through. It does not resist loosening from vibration. If the connection sees vibration or needs to stay tight without a locking nut, add a split or external tooth lock washer and keep the flat washer underneath it as the bearing surface.
3) Can I use Metallics SW70B washers for grounding connections?
A plain flat washer is a bearing surface, not a bonding device. Zinc plated steel flat washers go under the screw head to spread load; they are not a substitute for a star or paint piercing washer where you need to cut through finish to make a ground path, and they are not a listed grounding component. Use the SW70B for mechanical fastening and specify a proper bonding washer or lug where the connection has to carry fault current.
4) Where are Metallics SW70B washers made?
Country of origin on the SW70B is listed as multiple, so the washers may come from more than one source country depending on the production run. Buyers with a domestic sourcing requirement on a public job should treat this as an imported commodity fastener.
