Metallics JRMB87 – Frequently Asked Questions
1) What thread size and length are the Metallics JRMB87 machine screws?
They are 8-32 by 1-1/4 inch machine screws. The 8-32 designation means a #8 diameter with 32 threads per inch, so they thread into a tapped 8-32 hole or take a standard 8-32 nut. Usable grip is the full 1-1/4 inch shank under the round head.
2) Will an 8-32 x 1-1/4 machine screw work for mounting device boxes and cover plates?
8-32 is the standard machine screw thread for electrical device and box mounting, and this one is stocked as an electrical fastener. At 1-1/4 inches it is longer than the short screws that ship with a device, which is what you want when you're reaching through a thick plaster ring, a mud ring, or stacked spacers. If you are landing in a shallow tapped hole, a shorter 8-32 is the better choice so you aren't bottoming out.
3) Are the JRMB87 screws solid brass or just brass plated?
The JRMB87 is a brass machine screw, called out as MS Br (machine screw, brass) in the product description. Brass is the usual pick where you need a non-ferrous, non-magnetic fastener or want it to match brass hardware and cover plates.
4) What driver do I need for these 8-32 brass screws?
A flat blade screwdriver. The head is round head slotted (Rh Sl), so there is no Phillips or square recess. Brass is softer than steel, so keep the blade filling the slot and don't overdrive it.
5) How many screws come in a jar of Metallics JRMB87?
100 screws per jar. Metallics packs this item in a jar rather than a box or bag, which is what electricians and maintenance crews want on a bench or in a van drawer where you're grabbing a few at a time.
6) Are brass machine screws OK where I need a non-sparking or non-magnetic fastener?
Brass is non-magnetic and non-sparking, which is why it gets specified around instrumentation, compasses, and some hazardous or wet locations. It is softer than steel though, so for anything carrying real structural load or high torque, use a steel machine screw instead of the JRMB87.
7) What is the manufacturer part number for these Metallics brass round head screws?
Metallics part number JRMB87. That is the number to quote for the 8-32 x 1-1/4 round head slotted brass machine screw in the 100-count jar.
