Metallics SW75G5M – Frequently Asked Questions
1) What size bolt or rod do Metallics SW75G5M flat washers fit?
The SW75G5M is a 3/8 inch flat washer, so it is sized for 3/8-16 bolts and 3/8 inch threaded rod, which is the common rod size for conduit and strut hanging in commercial electrical work. It is a plain flat washer, not a lock washer, so it spreads bearing load under the nut or bolt head rather than resisting loosening.
2) Are these 3/8 washers OK for damp or outdoor electrical installs?
They are galvanized steel, so the zinc coating gives reasonable corrosion resistance for damp interior locations, unheated spaces and typical sheltered outdoor use. For continuous wet service, coastal exposure or chemical environments, stainless is the better call.
3) How many washers come in a box of Metallics SW75G5M?
They ship as a box of 5,000 pieces, which is a bulk pack intended for crews running strut, hangers and panel work rather than a small job count. There is one orderable configuration, model SW75G5M.
4) Is a flat washer or a lock washer the right choice under a 3/8 nut?
A flat washer like the SW75G5M distributes clamp load and protects the surface of strut, channel or sheet metal from being chewed up by the nut. It does nothing to stop a nut backing off under vibration. On equipment that vibrates, use a flat washer against the material and add a split lock washer or a locking nut above it.
5) Will galvanized washers react with stainless or aluminum hardware?
Mixing a galvanized steel washer with stainless fasteners or aluminum channel sets up a dissimilar-metal couple, and in wet locations the zinc will sacrifice first. Indoors and dry, it is routine practice. If the assembly stays wet, match the washer to the fastener material instead.
