Metallics JRM19 – Frequently Asked Questions

1) Does the JRM19 round head combo screw take a flat blade or a Phillips driver?
Either one. The combo head is slotted and Phillips in the same head, so a crew carrying only one screwdriver can still set it. The Phillips recess takes a #2 driver, and the slot runs 0.050 to 0.060 inch wide and 0.065 to 0.087 inch deep for a standard flat blade.
2) Are Metallics JRM19 machine screws Buy American or ARRA compliant for a government job?
No. The JRM19 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing requirement, this screw will not satisfy it and you need a domestically produced fastener.
3) How much does a round head screw stand off the surface, and will it clear a cover plate?
The round head on the JRM19 sits 0.123 to 0.137 inch above the surface with a head width of 0.334 to 0.359 inch. That is a domed, proud head, not flush. If you need the fastener to sit flat or let a cover plate seat against it, specify a flat head screw instead.
4) Is the Metallics JRM19 strong enough for structural or load-bearing mounting?
It is a steel screw with a 60,000 psi minimum tensile strength and a hardness of Rockwell B70-B100, made from AISI 1006 to 1022 steel. That is standard low-carbon machine screw material, fine for mounting devices, brackets, straps and covers. For load-bearing or high-torque connections, use a graded bolt rather than a machine screw.
5) Can I use these zinc plated screws outdoors or in a damp location?
The JRM19 is steel with a zinc finish, which gives corrosion resistance for indoor and dry or occasionally damp conditions. Zinc plating is not a marine or sustained-wet finish, so for exterior, coastal or washdown areas go with a stainless machine screw in the same 10-24 x 3/8 size.
6) How do these Metallics 10-24 screws come packaged, and what is the minimum I can buy?
They ship in a jar of 100, and 100 is the order minimum. That jar format is what most electrical contractors keep on the truck or on the shop shelf for restocking a bin.
7) What does a jar of 100 of these screws weigh for shipping or stocking purposes?
A jar of the 10-24 x 3/8 round head combo screws weighs 0.45 lbs. Light enough that most buyers add several sizes to one order without changing freight class.
