Metallics JSRM42 – Frequently Asked Questions

1) What thread size and length are the Metallics JSRM42 machine screws?
The JSRM42 is a 1/2-13 x 1-1/2 inch machine screw, so 1/2 inch nominal diameter with 13 threads per inch (UNC coarse) and a 1-1/2 inch shank length. It mates with any 1/2-13 nut or tapped hole.
2) How many Metallics JSRM42 screws come in a pack, and how are they packaged?
They ship in a jar, with a 50-count order minimum. So the smallest buy is 50 screws, which is the standard jar quantity for this item.
3) Will a round head slotted machine screw sit flush in a countersunk hole?
No. The JSRM42 has a round head, which is a domed head that sits on top of the surface, not in it. If you need the head flush with the material, you want a flat head machine screw in a countersunk hole instead. Drive is a single slot, so a standard flat-blade screwdriver turns it.
4) Will a 1/2-13 machine screw thread into sheet metal or wood?
No. A machine screw like the JSRM42 has a blunt, uniform machine thread and needs a mating nut or a pre-tapped 1/2-13 hole. It will not form its own thread in sheet metal, wood, or masonry. For those, use a self-tapping sheet metal screw, a lag, or an anchor.
5) Are these stainless screws okay for outdoor or damp electrical enclosures?
The JSRM42 screws are 18-8 stainless, the austenitic grade normally specified for wet and outdoor use because it resists rust without plating. Fine for exterior boxes, damp locations, and washdown areas. For salt spray or coastal marine exposure, 316 stainless is the step up.
6) What is the tensile strength and hardness of these 18-8 stainless machine screws?
Tensile strength is 80,000 psi minimum with a hardness of Rockwell B85 to B95. Worth noting that stainless machine screw strength values are approximations, since there is no single performance standard for stainless machine screws, so for a structural or load-rated connection use a fastener spec'd to a graded standard instead.
7) Do these Metallics screws meet Buy American or ARRA requirements for a public project?
The JSRM42 is flagged compliant for both Buy American and ARRA. Country of origin is China, so if your project specifies domestic melt and manufacture rather than the compliance flag, confirm the requirement language before you submit these.
8) Is a slotted drive a problem if my crew is driving these with impact drivers?
Yes, it can be. The JSRM42 uses a single slotted drive, and slotted heads cam out easily under power tools, especially on a 1/2 inch diameter screw that needs real torque. Hand-drive with a properly sized flat blade, or specify a Phillips, hex, or socket head screw if the work is going in with drivers.
9) Can I get this Metallics round head slotted screw in other lengths or diameters?
Yes. The JSRM42 covers 1/2-13 x 1-1/2 inch, and other sizes and quantities in the same SRM series of round head slotted stainless machine screws are available by request.
10) How much does a jar of Metallics JSRM42 screws weigh for shipping?
The jar is listed at 5.59 lbs, with jar dimensions of 5.75 in by 3.5 in by 3.5 in. Useful if you are consolidating a parts order or stocking a service van bin.
