Metallics JRM74SLT – Frequently Asked Questions
1) What thread size and length are the Metallics JRM74SLT machine screws?
The JRM74SLT is a 5-40 machine screw, 1-1/2 inches long, with 40 threads per inch. The 5-40 size is a #5 diameter machine screw thread, so it takes a #5-40 tapped hole or nut, not a sheet metal or wood application.
2) Are these Metallics round head slotted screws Buy American compliant?
Metallics lists the JRM74SLT as both Buy American and ARRA compliant, with China as the country of origin. If your project spec requires domestic melt and manufacture rather than the compliance designation, confirm that distinction with your specifier before submitting.
3) Will zinc plated steel machine screws hold up outdoors or in a damp location?
The JRM74SLT is zinc plated carbon steel, which is meant for dry interior work such as device and enclosure assembly. Zinc plating gives limited corrosion resistance and will rust in wet, exterior, or washdown conditions. For those openings use a stainless machine screw of the same 5-40 x 1-1/2 size instead.
4) How strong is a 5-40 steel zinc machine screw from the Metallics JRM series?
Rated at 60,000 psi minimum tensile strength, with a hardness of Rockwell B70 to B100. The steel is in the AISI 1006 to 1022 range, which is low carbon steel, so these are general purpose fasteners rather than a substitute for a graded high strength screw in a structural or vibration-loaded connection.
5) How are the Metallics 5-40 slotted machine screws packaged and what is the minimum order?
They ship in a jar of 100 pieces, and 100 count is the order minimum. The packed jar weighs 0.39 lbs. Metallics notes other sizes and quantities are available by request.
6) Is a round head slotted screw the right choice, or should I use a flat head?
Round head sits proud of the surface with a domed crown, so it is for through-bolting plates, straps, and covers where no countersink exists. If the part is countersunk and the head has to finish flush, a round head will not seat, and you need a flat head screw in the same 5-40 x 1-1/2 size. The slotted drive here matches a standard flat blade screwdriver, which is the common field driver on electrical device work.
7) Can I use these for electrical device and enclosure assembly?
That is exactly the intended use. Metallics groups the JRM74SLT with its electrical supply fasteners, and a 5-40 slotted round head in a 1-1/2 inch length is used for mounting devices, covers, plates, and hardware into tapped holes in boxes and enclosures. At 1-1/2 inches it is a long shank, so make sure your tapped hole or nut engagement is deep enough to take the full thread or you will have excess screw standing out behind the connection.
