Metallics JRM16SLT – Frequently Asked Questions

1) Will a 5-40 machine screw thread into a standard 5-40 tapped hole or nut?
Yes. The Metallics JRM16SLT is a 5-40 machine screw, meaning a #5 diameter with 40 threads per inch, which is the standard coarse (UNC) pitch for a #5 screw. It mates with any 5-40 tapped hole, 5-40 nut, or device strap drilled and tapped to that thread. If your hole measures out as 5-44, this screw will not run in.
2) Will zinc plated steel machine screws hold up outdoors or in a damp location?
The JRM16SLT is zinc plated carbon steel, which is a mild indoor corrosion coating, fine for panels, boxes, and dry interior work. For wet, washdown, or exterior locations use a stainless 5-40 round head slotted screw instead. Note that tensile values published for stainless machine screws are approximations, since there is no single performance standard for them.
3) Do I need a Phillips driver for these Metallics 5-40 screws?
No. These are slotted drive, so a flat-blade screwdriver is what you want, the same blade electricians use on terminal screws. Metallics also builds combination (combo) head fasteners, but the JRM16SLT is slotted only.
4) How strong are these 5-40 steel machine screws?
Minimum tensile strength is 60,000 psi, with hardness in the Rockwell B70 to B100 range, made from low carbon steel in the AISI 1006 to 1022 range. That is standard commercial low carbon machine screw material, suitable for mounting devices, covers, and brackets, not for structural or high torque load paths.
5) How do these Metallics machine screws come packaged, and is there a minimum order?
The JRM16SLT ships as a jar of 100 pieces, and 100 count is the order minimum. The packed jar weighs 0.2 lbs. Metallics states other sizes and quantities are available by request.
6) Do these screws meet Buy American or ARRA requirements for a public project?
The JRM16SLT carries both ARRA and Buy American compliance flags in the manufacturer's data, with country of origin listed as China. Agencies vary in how they treat that pairing, so match the flags against your project's specific procurement clause before you submit.
7) What is a 5-40 round head slotted machine screw actually used for in electrical work?
Machine screws like the JRM16SLT thread into pre-tapped holes or nuts rather than cutting their own thread in wood or sheet metal. The #5 diameter is a small size used for device, cover, and small bracket attachment inside boxes and enclosures. If you are fastening into sheet metal with no tapped hole, you want a self-tapping sheet metal screw instead.
