Metallics RSB106 – Frequently Asked Questions

1) Does the Metallics RSB106 stove bolt come with nuts, or do I have to buy those separately?
Nuts are included. Each RSB106 1/4-20 x 3 inch round head stove bolt ships with a hex machine screw nut, which is the nut style cut specifically for machine screw threads rather than a standard hex bolt nut. Nothing else is needed to make up the joint other than a washer if your application calls for one.
2) Will a 1/4-20 stove bolt thread into a standard 1/4-20 tapped hole or coupling nut?
Yes. The thread is 1/4-20 right hand, 20 threads per inch, cut to ANSI B18.6.3, so it mates with any standard 1/4-20 internal thread, whether that is a channel nut, a tapped enclosure boss, or a coupling nut. No left hand or oddball pitch to watch for.
3) What is the strength rating on the Metallics RSB106 stove bolt?
60,000 psi minimum tensile, made from AISI 1006 to 1022 carbon steel at Rockwell B70 to B100. That is standard commercial machine screw material, fine for strut, box, bracket, and general mounting work. It is not a graded structural fastener, so do not substitute it where a Grade 5 or Grade 8 bolt is specified.
4) What size driver do I need for the Metallics RSB106 1/4-20 stove bolt?
It takes a #4 Phillips bit, or a flat blade if you prefer. The head is a combo drive with both a slot and a Phillips recess, so one bolt works off either tool. The slot runs 0.064 to 0.075 inch wide and 0.082 to 0.109 inch deep, so a medium cabinet-tip screwdriver seats properly without camming out.
5) Is a zinc plated steel stove bolt OK for outdoor or damp locations?
The RSB106 is carbon steel with a zinc finish, which is a dry-location plating. It holds up fine inside panels, enclosures, and conditioned mechanical spaces. For wet, exterior, or corrosive areas you want stainless or hot dip galvanized hardware instead, because zinc plate will eventually bloom and the steel underneath will rust.
6) Do these Metallics stove bolts qualify for a Buy American or ARRA job?
No. The RSB106 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded work with domestic sourcing requirements you will need a domestically produced fastener instead.
7) What trades actually use a round head combo stove bolt like this?
Metallics lists the RSB106 for electrical, plumbing, heating, and air conditioning work. In practice it is the bolt you reach for hanging boxes and brackets, fastening to strut, securing covers and panels, and general MRO assembly where you need a through-bolt with a nut rather than a thread-cutting screw.
8) How are these stove bolts packaged and what is the smallest quantity I can buy?
The RSB106 sells in a 100 piece minimum, packaged as a jar/clamshell unit rather than loose counts. If you need a different length, diameter, or pack count in the RSB stove bolt line, Metallics makes other sizes and quantities available by request.
