Metallics RM22JB – Frequently Asked Questions
1) Is the RM22JB a machine screw or a self-tapping sheet metal screw?
It is a machine screw. The threads run the full 1/4-20 machine thread form and will not cut their own hole, so the material has to be tapped 1/4-20 already or you need a nut on the back. If you are fastening into bare sheet with no prepared thread, a self-drilling or sheet metal screw is the right part instead.
2) Will a Phillips or a flat blade driver work on the RM22JB screw head?
Either one. The RM22JB has a combination drive head, meaning the recess takes both a Phillips bit and a slotted screwdriver. That matters on a panel job where you are working one-handed in a box and only carrying one driver.
3) Are these Metallics screws zinc plated steel, and can I use them outdoors?
These are steel screws with a zinc plating. Zinc plating is a mild indoor corrosion coating, so it is fine for panels, enclosures, and interior electrical work, but it is not a wet or coastal exterior finish. For outdoor or damp locations, go with a stainless machine screw in the same 1/4-20 x 3/8 size instead.
4) Do the RM22JB 1/4-20 screws come with nuts?
No. The RM22JB is sold as screws only, 500 pieces of the 1/4-20 x 3/8 round head screw. If you are through-bolting rather than threading into a tapped hole, order 1/4-20 nuts and any washers separately.
5) How many screws come in a box of Metallics RM22JB?
500 pieces per box. That is a bulk shop quantity for electricians who are mounting devices, covers, and brackets repeatedly, not a small job pack.
6) What is the Metallics part number for 1/4-20 x 3/8 round head combo machine screws?
RM22JB. One model covers this size: 1/4-20 x 3/8, round head, combination drive, zinc plated steel, 500 to a box.
