Metallics RSB90 – Frequently Asked Questions

1) Does the Metallics RSB90 stove bolt come with nuts, or do I have to buy those separately?
Each Metallics RSB90 8-32 x 2-1/2 inch stove bolt ships with a hex machine screw nut, so no separate nut purchase is needed. The nut is the machine screw pattern, sized specifically for machine screw threads rather than the coarser nuts used on standard bolts.
2) Will this 8-32 bolt meet a Buy American requirement on a federally funded job?
No. The Metallics RSB90 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a job carrying domestic sourcing language, this is not the fastener to submit.
3) What driver do I need for an 8-32 round head combo stove bolt?
The RSB90 has a combo head, so either a flat blade or a #2 Phillips will drive it. The Phillips recess runs 0.165 to 0.178 inch across at 0.101 inch deep, and the slot is 0.045 to 0.054 inch wide, so a standard cabinet tip screwdriver seats in the slot without camming out. Handy when you are working one handed in a box and only have one bit on the driver.
4) Will a round head 8-32 screw sit flat against a device plate or box ear without binding?
The round head measures 0.287 to 0.309 inch across and only 0.107 to 0.12 inch tall, so it bears on the surface rather than sinking in. That low profile clears most cover plates and box ears, but it is a protruding head, not a countersunk one. If the drawing calls for a flush face, you need a flat head machine screw instead.
5) Is the Metallics RSB90 made to a recognized dimensional standard for machine screws?
Head and drive dimensions follow ANSI B18.6.3, the standard for inch series machine screws, and the steel is in the AISI 1006 to 1022 range. Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70 to B100. Those are the numbers a spec reviewer or an institutional buyer will ask for.
6) How many 8-32 x 2-1/2 stove bolts come in a jar, and what is the minimum order?
These are sold by the jar of 100 pieces, with 100 as the order minimum. Packaging is a square plastic jar, which is what keeps loose hardware from migrating around a service van.
7) Is a 2-1/2 inch stove bolt long enough to go through a box, a bracket, and still take a nut?
At 2-1/2 inches of overall length under the round head, the RSB90 has enough reach to pass through stacked material and leave thread for the included hex nut. Keep in mind it is a through bolt setup, not a self tapping screw, so you need access to both sides of the assembly to run the nut on.
8) Is the RSB90 right hand thread, and what is the thread pitch?
Right hand thread at 32 threads per inch, the standard 8-32 machine screw pitch. It mates with any 8-32 tapped hole or 8-32 nut, including the tapped ears on standard device boxes.
