Metallics SW77B – Frequently Asked Questions
1) Are the Metallics SW77B washers plated for corrosion resistance?
They are steel with a zinc plating. That handles dry interior electrical and mechanical work, damp locations with normal humidity, and covered exterior runs. For direct weather exposure, wet process areas, or coastal installs, step up to stainless or hot dip galvanized washers instead.
2) Should I use a flat washer or a lock washer on 5/8 threaded rod hangers?
Different jobs. A flat washer like the SW77B spreads the load across the surface and protects the material under the nut, which is what you want against strut, channel, or sheet steel. A split lock washer resists loosening from vibration but does nothing for bearing area. On vibrating equipment hangers, many installers use both: flat washer against the material, lock washer under the nut.
3) Is the Metallics SW77B washer made to an ANSI dimensional standard?
Yes, the SW77B 5/8 flat washer is built to ANSI dimensional standards, so the inside and outside diameters and thickness match what a drawing or submittal calling out an ANSI 5/8 flat washer expects. That matters on institutional and government work where the spec names the standard rather than a part number.
4) How much does a box of 1800 Metallics SW77B 5/8 washers weigh and how big is the carton?
The box runs 46.85 lbs and measures 9 x 9 x 6.13 inches. Worth knowing before you load it onto a cart or a scaffold, and if you are shelving it in a van bin, that is a dense, compact carton rather than a bulky one.
5) What part number do I order for Metallics 5/8 zinc flat washers in bulk?
Order Metallics SW77B. That is the manufacturer part number for the 5/8 flat, steel zinc washer supplied 1,800 to a box.
