Metallics SW73B – Frequently Asked Questions
1) What size bolt do Metallics SW73B flat washers fit?
The SW73B is a 1/4 inch flat washer, so it is sized for 1/4-20 and 1/4-28 bolts, screws, and threaded rod. It is a plain flat washer, used to spread load and protect the surface under a nut or bolt head, not a lock or spring washer.
2) Are the SW73B washers plated for use in damp or outdoor locations?
They are zinc plated steel. The zinc gives moderate corrosion resistance for dry and normally damp interior work such as strut, panel, and box mounting. For wet, exterior, or corrosive environments, hot dip galvanized or stainless washers are the usual call instead.
3) How many washers come in a box of Metallics SW73B?
One box holds 10,000 pieces of the 1/4 inch zinc plated flat washer, packed as a single box. That is bulk-shop quantity, aimed at electrical contractors and MRO stockrooms doing repeat strut and box mounting rather than a one-off repair.
4) Will a 1/4 inch flat washer work with 1/4 inch strut nuts and channel hardware?
Yes. The SW73B matches 1/4 inch channel hardware, strut nuts, and 1/4-20 threaded rod, and the plain flat profile seats on strut, sheet metal, and enclosure flanges where you need bearing area under the nut. If you also need vibration resistance, pair it with a separate lock washer or locknut, since this is a flat washer only.
5) How much does a 10,000-count box of SW73B washers weigh and what are the carton dimensions?
The box runs 42.8 lbs, with a stated 9 x 9 x 6.13 inch size. Worth knowing before you put it on a shelf or hand it up a ladder, it is a two-hand lift and better broken down into a parts bin or pouch on site.
6) What is the Metallics part number and where are these washers made?
Order by MPN SW73B from Metallics. Country of origin is listed as multiple, so pieces within a box can come from more than one source plant. For jobs with a domestic-origin requirement, that matters at submittal time.
