Metallics JRMB75 – Frequently Asked Questions
1) Are these 4-40 screws brass or steel?
Brass. The JRMB75 is a brass machine screw, which is what electricians typically want for device and plate work where a non-magnetic, corrosion-resistant fastener matters.
2) What head style and driver do the Metallics JRMB75 screws take?
Round head with a single slot, so you drive them with a flat blade screwdriver. The domed round head sits above the surface rather than flush, so don't use these where a countersunk flat head is called for.
3) Will a 4-40 x 1 inch machine screw work for mounting electrical devices and cover plates?
4-40 is a common thread for small electrical hardware, and the JRMB75 brass screws are sold through the electrical channel for that kind of work. The thing to check is length: at 1 inch these are long for a flush switch plate, and they suit deeper mounting, standoffs, or stacked assemblies. For a plain device plate screw you generally want a shorter 6-32.
4) Do the Metallics JRMB75 screws come with nuts?
No. The jar contains 100 brass 4-40 x 1 inch round head slotted machine screws only. If you're fastening through a panel rather than into a tapped hole, order 4-40 nuts and any washers separately.
