Metallics RM102-1M – Frequently Asked Questions
1) Are these 1/4-20 screws machine screws or self-tapping sheet metal screws?
Machine screws. The RM102-1M is a straight-threaded 1/4-20 machine screw, so it needs a mating tapped hole, a nut, or a channel nut. It will not cut its own thread in sheet metal the way a self-drilling or sheet metal screw does, so for unthreaded sheet you need a tapping screw instead.
2) What head and driver do the Metallics RM102-1M screws use?
Round head with a combination drive, so a Phillips bit or a flat blade both work. The round head sits proud of the surface rather than flush, so it is not a substitute for a flat head screw in a countersunk hole.
3) Can these zinc plated screws be used outdoors or in a damp location?
The RM102-1M is steel with zinc plating, which is a mild indoor corrosion coating. It is fine in dry interior electrical work (boxes, covers, strut, panel hardware) but for exterior, wet, or washdown locations you want hot dip galvanized or stainless 1/4-20 hardware instead.
4) Will 1/4-20 x 1-1/4 machine screws work with strut channel nuts?
Yes, as long as the channel nut is 1/4-20. Strut channel nuts are commonly supplied in 1/4-20, 3/8-16, and 1/2-13; the RM102-1M matches the 1/4-20 size. At 1-1/4 inches of length, allow for the thickness of whatever you are clamping plus full thread engagement in the nut.
5) How many screws come in the Metallics RM102-1M box?
1,000 pieces per box. That is a bulk contractor pack, which is how electricians buy 1/4-20 round head machine screws for repetitive box, cover, and strut work rather than counting out small packs per job.
6) Do these screws come with nuts or washers?
No. The RM102-1M box is screws only, 1,000 of them. If your application is not into an already tapped hole or a channel nut, order 1/4-20 hex nuts and any flat or lock washers separately.
