Metallics JRM66SLT – Frequently Asked Questions

1) What thread size and length are the Metallics JRM66SLT machine screws?
The JRM66SLT is a 3/8-16 machine screw, 1 inch long. That's 16 threads per inch on a 3/8 inch diameter, so it mates with a 3/8-16 tapped hole or a 3/8-16 nut. Coarse 3/8 thread is the common size for strut, box, and channel hardware, so check whether your hole is 3/8-16 before ordering.
2) How strong is a 3/8-16 Metallics machine screw, and what is it made from?
Tensile strength is 60,000 psi minimum, with hardness in the Rockwell B70 to B100 range. The stock is low carbon steel to AISI 1006 through 1022. That is standard low carbon commercial machine screw strength, suitable for general mounting and bracket work. If a drawing calls for a graded high strength fastener, such as a Grade 5 or Grade 8 bolt, this screw does not meet that.
3) What driver do I need for these Metallics round head machine screws?
A flat blade screwdriver. The JRM66SLT is slotted drive, with a slot 0.081 to 0.094 inch wide and 0.117 to 0.155 inch deep. Match the blade thickness to that slot width so you don't chew the head out under torque. If your crew is running impact drivers or Phillips bits, these aren't the screws for that workflow.
4) How many Metallics JRM66SLT screws come in a pack, and can I buy just a few?
They ship 100 to a jar, and 100 count is the order minimum, so a handful is not an option. The packed jar weighs 4.03 lbs. For MRO stockrooms and service trucks, a jar of 100 in a single thread size is the typical way these get carried.
5) Do the Metallics JRM66SLT screws meet Buy American or ARRA requirements on a public job?
The JRM66SLT carries a compliant flag for both Buy American and ARRA. Country of origin is China. On federally funded work where the specification language controls, hand both of those facts to your compliance reviewer before you submit, because the governing clause varies by project.
6) Do these machine screws come with nuts or washers?
No. The JRM66SLT is supplied as screws only, 100 in a jar. If you are through-bolting rather than threading into a tapped hole, order 3/8-16 hex nuts and 3/8 flat or lock washers separately.
7) Is a machine screw the right choice, or do I need a sheet metal or self tapping screw?
A machine screw like the JRM66SLT has a uniform 3/8-16 machine thread with a blunt end, so it needs a pre-tapped hole or a mating nut. It will not cut its own thread. If you are fastening into unthreaded sheet, strut, or a drilled hole with no tap, use a self tapping or sheet metal screw instead. For a tapped enclosure boss, mounting plate, or channel nut, the machine screw is correct.
