Metallics JSRM43 – Frequently Asked Questions

1) What thread does the Metallics JSRM43 machine screw take, and will it run into a standard 1/2-13 nut?
The JSRM43 is a 1/2-13 screw, meaning a 1/2 inch nominal diameter at 13 threads per inch, which is the standard UNC coarse pitch for that diameter. It will thread into any 1/2-13 nut or tapped 1/2-13 hole. Overall length is 2 inches.
2) Are these stainless machine screws OK for outdoor or damp electrical work?
They are 18-8 stainless, the common austenitic grade used where plated steel would rust, so they hold up in damp interior and general exterior conditions. 18-8 is not the grade to pick for chloride-heavy marine exposure; 316 is the step up there.
3) Is a 1/2-13 machine screw the right choice for anchoring into concrete or wood?
No. A machine screw has a uniform straight machine thread and needs a nut or a tapped hole to hold, so it is for metal-to-metal fastening, panels, enclosures, and strut hardware. For concrete you want an anchor, and for wood a lag or wood screw with a tapered self-forming thread.
4) How much usable grip do I get out of a 2 inch round head machine screw?
Machine screws are measured from under the head on a round head, so the full 2 inches is shank length and the round head sits proud on top of the work. Thread runs the length, so you can stack material plus nut anywhere up to roughly 2 inches of grip. If you need the head flush, a round head is the wrong profile.
5) What strength can I count on from the JSRM43 stainless screw?
Tensile strength is listed at 80,000 psi minimum with a hardness of Rockwell B85-B95. Note that stainless machine screw tensile figures are approximations, since there is no single performance standard for stainless machine screws. For a known, graded tensile value in a structural connection, use a graded steel bolt instead.
6) How are the Metallics JSRM43 screws packaged and what is the minimum I can order?
They ship in a jar, with an order minimum of 50 count. Total weight for that quantity is 6.52 lbs. Useful if you are stocking a shop bin rather than buying a handful.
7) Will these screws satisfy a Buy American or ARRA requirement on a government job?
The JSRM43 carries both ARRA compliant and Buy American compliant flags in its product data, with country of origin listed as China. Public-agency buyers working to a strict domestic-content clause should read both of those together, since the compliance flag and the origin are separate facts about the same part.
8) Can I mix these stainless screws with galvanized or plated steel hardware?
It works mechanically, since the 1/2-13 thread mates with any 1/2-13 nut regardless of plating. Be aware that pairing 18-8 stainless with zinc or galvanized steel in a wet location sets up galvanic action that eats the zinc first. For exposed outdoor assemblies, keep the nuts and washers stainless too.
9) Does Metallics offer this round head slotted screw in other lengths or diameters?
The SRM series covers other sizes and quantities by request; JSRM43 itself is fixed at 1/2-13 x 2 inches in 18-8 stainless. If you need a shorter grip or a smaller diameter in the same round head slotted pattern, ask for the matching SRM part.
