Metallics RSB72SS – Frequently Asked Questions

1) Does the Metallics RSB72SS stove bolt come with nuts, or do I have to order those separately?
Hex nuts are included with the RSB72SS. Each 3/8-16 x 1-1/4 in. round head bolt ships with a matching 18-8 stainless hex nut, so there's nothing else to add for a through-bolted connection. The nuts are stainless to match the screw, which is what you want anywhere the assembly sees moisture or corrosive conditions.
2) Is 18-8 stainless the right choice for outdoor or wet-location electrical work?
That's exactly what 18-8 stainless is for. The RSB72SS uses 18-8 stainless for both the bolt and the nut, which is the grade specified where parts are subject to corrosive conditions, wet locations, coastal air, or washdown areas. If you pair a stainless screw with a plated steel nut you reintroduce the rust point, which is why the matching stainless nut is packed with it.
3) How strong is a stainless stove bolt like this compared to a grade 5 steel bolt?
The RSB72SS is rated at 80,000 psi minimum tensile with a hardness of Rockwell B85-B95. That puts it well under a grade 5 carbon steel bolt, which is normal for stainless. Metallics also notes that tensile values on stainless screws are approximations, since there is no single performance standard for stainless machine screws. Use it for corrosion resistance and general fastening, not for structural or high-preload connections.
4) Do these Metallics stove bolts meet Buy American requirements for a government or institutional job?
The RSB72SS is flagged both ARRA compliant and Buy American compliant, which is what a public-works or federally funded spec asks for. Head and thread geometry conform to ANSI B18.6.3, with SAE as the material standard, so it will also satisfy a drawing that calls out a dimensional standard for round head machine screws.
5) Can I use a stove bolt instead of a machine screw for mounting electrical boxes and strut?
A stove bolt is a machine screw with a blunt end and a coarse thread, meant to be run through a clearance hole and captured with a nut rather than threaded into tapped material. The RSB72SS ships with that nut. If you're threading into a tapped hole in a box or an enclosure boss, a stove bolt works but you get no better hold than any 3/8-16 machine screw, and the included nut goes unused. For through-bolting box flanges, brackets, and strut fittings, this is the right style.
6) How are these sold, and is there a minimum order quantity?
The RSB72SS comes in a clamshell pack with an order minimum of 100 count. Metallics also offers other sizes and quantities in the RSB stove bolt series by request, so if you need a different length or diameter in the same 18-8 stainless build, that's available.
