Metallics RSBK4 – Frequently Asked Questions

1) What exactly comes in the Metallics RSBK4 stove bolt kit?
The RSBK4 is a 324-piece tray of 1/4-20 round head stove bolts with matching hardware. Bolt lengths run 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch (35 of the 1/2 inch, 30 of the 3/4, 20 of the 1 inch, 15 of the 1-1/4, 12 each of the 1-1/2 and 2 inch). It also includes 100 1/4-20 hex nuts, 50 1/4 SAE flat washers and 50 1/4 lock washers, so you can make up a bolted connection without pulling parts from another bin.
2) Do these 1/4-20 bolts thread into standard 1/4-20 strut channel nuts and fittings?
Yes. Thread is 1/4-20 UNC, 20 threads per inch, made to ANSI B18.6.3, so it mates with any standard 1/4-20 internal thread (channel nuts, spring nuts, tapped brackets) as well as the 1/4-20 hex nuts supplied in the tray.
3) How much clamping load will these stove bolts take on a conduit or box support?
Steel bolts with a 60,000 psi minimum tensile strength and Rockwell B70 to B100 hardness, made from AISI 1006 to 1022 steel. That is standard low-carbon machine screw material, fine for mounting boxes, straps, hangers and panel work, but it is not a grade 5 or grade 8 structural bolt. For a load-bearing structural connection, step up to a hex cap screw in the proper grade.
4) Can I use this kit on a federally funded job with Buy American requirements?
No. The RSBK4 kit is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your project carries a domestic-content clause, source a domestically manufactured 1/4-20 machine screw assortment instead.
5) Will a Phillips bit drive these 1/4-20 stove bolts, or do I need a flat blade?
Either works. The heads are combination slotted/Phillips, so a #4 Phillips driver seats in the recess (0.255 to 0.268 inch diameter, 0.147 inch deep) and a flat blade fits the slot (0.064 to 0.075 inch wide, 0.082 to 0.109 inch deep). Handy on a ladder where you only brought one screwdriver.
6) Is the zinc finish on these stove bolts OK for a damp or outdoor location?
The bolts are steel with a zinc finish, which is a general-purpose corrosion coating for indoor and dry service. It will handle a mechanical room or an unheated space, but for direct weather exposure, wash-down, or coastal work you want hot-dip galvanized or stainless fasteners instead.
7) What trades actually use a 1/4-20 stove bolt kit like this?
Metallics lists the RSB series for electrical, plumbing, heating and air conditioning work. In practice that is mounting boxes and enclosures, hanging strut and channel, fastening straps and brackets, and duct and equipment attachment where a through-bolt and nut is wanted rather than a tapping screw. The included lock washers let you make up a joint that resists vibration on mechanical equipment.
