Metallics SSW13B – Frequently Asked Questions
1) Are Metallics SSW13B washers stainless steel or plated steel?
Stainless steel, not zinc-plated carbon steel. That matters on outdoor strut runs, rooftop equipment, wash-down areas, and coastal jobs where a plated washer rusts and stains the surface under it. Pair them with stainless bolts and nuts so you are not mixing dissimilar metals at the joint.
2) How many washers come in a box of Metallics SSW13B?
2500 pieces, packed in a box. That is bulk-quantity for an electrical contractor or MRO storeroom standardizing on 5/16 stainless hardware, not a job-count bag.
3) Can I use a 5/16 flat washer with 5/16 strut channel hardware and threaded rod?
Yes. A 5/16 flat washer spreads the load under the nut or bolt head on strut, channel, and 5/16 all-thread hanger assemblies, which is the common electrical rough-in use. The stainless material makes it suitable where the rod and channel are also stainless or where corrosion is a concern. For strut-specific bearing surface you may still want a channel nut or strut washer rather than a plain flat washer.
4) Is a flat washer or a lock washer the right choice for my 5/16 connection?
The SSW13B is a plain flat washer: it distributes load and protects the mounting surface, but it does nothing to stop a nut backing off. If the assembly sees vibration, add a split lock washer or a nylon-insert lock nut and keep the flat washer against the material. Many installers stack both, flat washer against the surface, lock washer under the nut.
5) Will a 5/16 stainless flat washer work in an outdoor or wet location?
Stainless construction is what makes this washer usable outdoors, in damp locations, and in wash-down environments where plated steel would bleed rust. Keep the whole fastener stack stainless; a stainless washer under a plated bolt still leaves the bolt as the corrosion point.
6) Does the Metallics SSW13B washer follow a standard dimensional spec?
The SSW13B is identified as an ANSI-standard flat washer in 5/16 size, so the inside diameter, outside diameter, and thickness follow the standard pattern rather than a proprietary one. Practically, that means it interchanges with other ANSI 5/16 flat washers already on the job.
