Metallics JRM39SLT – Frequently Asked Questions

1) Will a 6-32 x 5/8 in. round head machine screw work for mounting device plates and switches in an electrical box?
6-32 is the standard thread for mounting switches, receptacles and cover plates to outlet boxes, and the Metallics JRM39SLT is a 6-32 thread at 32 threads per inch with a 5/8 in. length. The 5/8 in. shank gives extra reach when a plaster ring, mud ring or thick wall finish pushes the device out from the box ears. The slotted drive works with a standard flat blade electrician's screwdriver.
2) How many Metallics JRM39SLT screws come in a jar?
They ship 100 to a jar, and 100 count is the order minimum, so one jar is the smallest buy. The jar pack keeps them contained on a service cart or in a van bin rather than loose in a bag.
3) Is a round head or a flat head machine screw the right choice for a cover plate?
Round head sits proud of the surface on an unprepared hole, which is what you want for box mounting, bracket work, and clamping where there is no countersink. The JRM39SLT head measures 0.24 to 0.26 in. across with a head height of 0.091 to 0.103 in., so it bears on the full surface of the part. If the hole is countersunk and the head has to finish flush, such as a decorative wall plate, use a flat head screw instead.
4) How strong are these zinc plated steel machine screws?
The JRM39SLT runs 60,000 psi minimum tensile strength with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial grade machine screw material, fine for device mounting, panel and bracket work. For structural or high load joints, specify a graded bolt rather than a machine screw.
5) Can zinc plated machine screws be used outdoors or in a damp location?
Zinc plating over steel is a mild corrosion barrier meant for dry interior service, which is where this screw belongs: panel interiors, device boxes, conditioned mechanical spaces. For wet locations, exterior boxes, or washdown and coastal environments, move to a stainless machine screw in the same 6-32 x 5/8 in. size.
6) Will a 6-32 machine screw thread into sheet metal or do I need a nut?
A machine screw has a straight machine thread, so it needs a tapped hole, a threaded box ear, or a matching 6-32 nut. It will not form its own thread the way a self tapping or sheet metal screw does. Outlet boxes and device yokes are already tapped 6-32, which is why this size drops straight in; for a plain drilled hole in sheet steel, pair it with a 6-32 nut or a tapped insert.
7) Do these Metallics screws meet Buy American or ARRA requirements on a public project?
The JRM39SLT is flagged compliant for both ARRA and Buy American in the product record, with country of origin listed as China. Procurement officers on federally funded work should take both of those together when they document the submittal.
8) What does a jar of 100 of these screws weigh for shipping?
A jar of the JRM39SLT comes in at 0.33 lbs. Easy to stock several sizes in a van without weight concerns.
