Metallics RMK832 – Frequently Asked Questions

1) What screw lengths are in the Metallics RMK832 #8-32 machine screw kit, and how many of each?
The RMK832 tray holds 370 screws in six lengths: 100 at 1/2 inch, 75 at 3/4 inch, 75 at 1 inch, 50 at 1-1/4 inch, 40 at 1-1/2 inch, and 30 at 2 inch. All are #8-32 round head, so the only variable from one compartment to the next is length.
2) Are the heads on these #8-32 screws low enough to sit under a device plate or in a countersunk hole?
No, these are round head screws, which sit proud of the surface. Head height is 0.107 to 0.12 inch and head width 0.287 to 0.309 inch, so the head crowns above the material rather than seating flush. For a countersunk hole you need a flat head machine screw instead; for a flush-looking cover plate, an oval or truss head.
3) Can I use this zinc plated steel screw kit outdoors or in a wet location?
Zinc plating on carbon steel is an indoor and dry-location finish. It resists corrosion in panels, cabinets, and conditioned spaces, but exposed outdoor, coastal, or washdown duty will eventually rust it. For those openings specify stainless machine screws rather than this steel zinc tray.
4) How strong are these screws, and can I use them to hang equipment brackets?
The steel is AISI 1006 to 1022 with a 60,000 psi minimum tensile strength and Rockwell B70 to B100 hardness. That is standard commercial-grade machine screw stock, fine for mounting control boxes, conduit straps, duct components, and equipment brackets into tapped holes or nuts. It is not a high-strength structural fastener, so anything calling out a graded bolt on the drawing needs a different part.
5) Does this Metallics screw kit come with nuts or washers?
No. The RMK832 tray is machine screws only, 370 of them across six lengths. If you are fastening through sheet metal without a tapped hole, order #8-32 hex nuts, lock nuts, or washers separately.
6) Do these Metallics fasteners meet Buy American or ARRA requirements for a public works job?
The RMK832 kit is flagged both ARRA compliant and Buy American compliant in the manufacturer's data, with country of origin listed as multiple. Institutional and government buyers working to those procurement clauses can reference those compliance flags.
7) How big is the Metallics 370-piece tray, and will it fit in a van drawer or service cart?
The tray measures 8 x 4.62 x 1.25 inches and weighs 2.28 lbs, so it drops into a shallow van drawer or tool bag pocket and stacks flat. The compartments keep the six lengths separated rather than loose in a bin.
8) Can I buy a single Metallics RMK832 kit or is there a case minimum?
One kit is the minimum. The RMK832 is sold each, so a single 370-piece tray is a complete order for a one-truck stock-up or a small MRO cabinet.
How fast can I get the Metallics RMK832 delivered?
