Metallics RM103B – Frequently Asked Questions
1) Will a 1/4-20 machine screw thread into a standard strut nut or channel nut?
Yes. The RM103B is a machine-threaded 1/4-20 fastener, so it mates with any 1/4-20 tapped hole, strut nut, channel nut or spring nut of that thread. Machine screws need a mating thread, they will not cut their own into sheet metal or wood.
2) Are zinc plated steel machine screws OK for outdoor or damp electrical work?
Zinc plated steel, like the RM103B, is a mild corrosion coating meant for dry indoor use. For exterior, wet locations or corrosive environments, step up to a stainless steel or hot dip galvanized 1/4-20 machine screw instead.
3) How many 1/4-20 x 1-1/2 machine screws come in a box of Metallics RM103B?
2,250 pieces per box. That is a bulk contractor pack, sized for shops standing up strut runs, panel and enclosure mounting, or bonding hardware across a job rather than a single repair.
4) Do the Metallics RM103B screws come with nuts or washers?
No. The RM103B box is screws only, 2,250 of them. You will need to order matching 1/4-20 hex nuts, flat washers or lock washers separately, or have the 1/4-20 tapped holes or channel nuts already in place.
5) What driver do I need for Metallics RM103B combination drive screws?
Combination head, so a #2 Phillips bit or a flat blade screwdriver both work. That is handy on service calls where you are not carrying a full bit set, and it lets a crew drive them by hand or with a cordless.
6) What grip length will a 1-1/2 inch machine screw give me?
The 1-1/2 inch length is measured under the round head, so your usable grip is 1-1/2 inches minus whatever the nut and washers consume. For thin sheet steel enclosures or strut channel, that leaves plenty of thread exposed; for stacked assemblies measure your total clamp-up before committing to this length.
