Metallics RM100B – Frequently Asked Questions
1) What head style and driver do the Metallics RM100B screws use?
Round head with a combination drive, so you can run them with either a flat blade or a Phillips bit. The round head sits proud of the surface rather than sinking flush, so these are not a substitute where a countersunk flat head is called for.
2) Are the Metallics RM100B 1/4-20 screws suitable for damp or outdoor electrical work?
They are steel with a zinc plating, which is a general indoor corrosion coating. For wet, coastal or chemically aggressive locations, step up to stainless steel fasteners instead of zinc plated steel.
3) How many screws come in the Metallics RM100B box?
3,000 pieces per box. That is a bulk contractor or MRO quantity, aimed at crews who consume 1/4-20 x 3/4 round head machine screws continuously rather than at a single-opening repair. If you only need a handful, a small count pack is the better buy.
4) Will the RM100B work as a 1/4-20 ground screw or box mounting screw?
It will thread into any 1/4-20 tapped hole, and at 3/4 inch under the head it gives enough engagement for typical box, bracket and strut nut applications. Note it is a plain zinc plated steel machine screw, not a green painted grounding screw, so where the spec calls specifically for an identified ground screw, order that part instead.
5) What is the Metallics part number for the 1/4-20 x 3/4 round head machine screw?
Order it as Metallics RM100B. One model covers the item, so there is no finish or size choice to specify beyond that number.
6) Do the RM100B machine screws come with nuts?
No. The RM100B is screws only, 3,000 pieces. If you are fastening through unthreaded material rather than into a tapped hole, order 1/4-20 nuts and any washers separately.
