Metallics RM104-1M – Frequently Asked Questions
1) What thread size and length are the Metallics RM104-1M machine screws?
They're 1/4-20 x 2 inch machine screws, round head with a combination (Phillips/slotted) drive, steel with zinc plating. The 1/4-20 designation means a 1/4 inch nominal diameter with 20 threads per inch, so they thread into any 1/4-20 tapped hole or nut.
2) Will a 1/4-20 machine screw thread into a drywall or wood stud like a wood screw?
No. The RM104-1M is a machine screw, which means a uniform 1/4-20 machine thread that needs a mating tapped hole, a nut, or a threaded insert. It will not hold in wood, drywall or unthreaded sheet metal on its own. For those substrates you want a wood screw, self-drilling sheet metal screw, or a drywall anchor instead.
3) How many screws come in the Metallics RM104-1M box?
One thousand pieces per box. It's a bulk pack for shops doing repetitive work, not a small hardware-store card of a dozen, so order with that count in mind.
4) Is the combination head on these screws driven with a Phillips or a flat screwdriver?
Either. CD means combination drive, so the round head takes both a Phillips bit and a flat blade. Handy on service calls where you don't control which driver is in the tech's pouch.
5) Are zinc plated steel machine screws OK for outdoor or wet locations?
These are steel with zinc plating, which is a corrosion coating meant for dry indoor and protected use. For exterior, damp, or washdown locations, step up to stainless steel fasteners instead, since zinc plating on carbon steel will eventually rust in standing moisture.
6) Are these the right screws for mounting electrical devices and box covers?
Yes, 1/4-20 round head machine screws are an electrical-trade fastener and that's how Metallics catalogues them. The 2 inch length gives you reach through thick covers, spacers, or stacked plates into a tapped hole or a nut on the back side. For shallow device-box tapped holes a shorter screw usually makes more sense.
7) Do nuts or washers come with the RM104-1M screws?
No, the box is screws only, 1000 of them. Since a machine screw needs something to thread into, plan on ordering 1/4-20 hex or machine screw nuts and any flat or lock washers separately if the hole isn't already tapped.
8) What part number do I order for Metallics 1/4-20 x 2 round head combo machine screws?
Order Metallics RM104-1M. That part number is the 1000 piece bulk box of 1/4-20 x 2 inch round head combination drive machine screws in zinc plated steel.
