Metallics JRBWS21 – Frequently Asked Questions
1) What size and type of screw is the Metallics JRBWS21?
It's a #10 x 1/2 inch wood screw with a round head and a slotted drive, in a brass finish. Order part number JRBWS21. The #10 diameter with a 1/2 inch length makes it a short fastener for surface-mounting into wood, not for anything that needs depth of bite.
2) Is the Metallics JRBWS21 a wood screw or a machine screw?
Wood screw. The WS in the description means wood screw, so it has a tapered shank and a coarse thread that cuts its own thread in wood. It will not thread into a tapped metal hole the way a 10-32 machine screw does, so if you're fastening into a device yoke or a metal box, you need a machine screw instead.
3) How many screws come in a jar of Metallics JRBWS21?
Each jar holds 100 screws. The jar pack is the standard way these are sold, so you're buying in hundreds rather than by the piece, which suits a service van or a shop bin.
4) Will a slotted round head brass screw work for mounting cover plates and electrical trim?
That's the intended use. The JRBWS21 is catalogued with electrical fasteners, and the slotted round head drives with a flat-blade screwdriver and seats on top of the material rather than countersinking, which is what you want for plates, straps, and trim where the head is meant to show. The brass finish matters when the screw stays visible.
5) Is 1/2 inch long enough to hold into a wood stud or joist?
A 1/2 inch screw gives you very little penetration once you subtract whatever thickness of strap, plate, or bracket sits under the head. It's for thin material held to wood, not for structural pull. If you're anchoring something that carries load into a stud, step up to a longer #10 wood screw.
