Metallics JSRM85P – Frequently Asked Questions

1) What size and thread is the Metallics JSRM85P machine screw?
JSRM85P is a 1/4-20 machine screw, 1-1/4 inches long, with 20 threads per inch. That is the standard coarse (UNC) pitch for 1/4 inch, so it mates with any 1/4-20 tapped hole or nut.
2) How much clearance does the round head need, and how wide does it sit on the panel?
The round head measures 0.443 to 0.472 inch across and stands 0.16 to 0.175 inch above the surface. If your detail calls for a flush face, this is the wrong head style, you would want a flat head in a countersunk hole instead. The round head does give you bearing area over a slightly oversized or slotted hole.
3) Are these Metallics stainless screws Buy American or ARRA compliant for a government job?
No. The JSRM85P is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a federally funded project with domestic-content requirements you will need a different fastener.
4) What screwdriver or bit do I need for these 1/4-20 round head Phillips screws?
A #3 Phillips driver. The recess is a Phillips with a gaging depth of 0.104 to 0.130 inch and a recess diameter of 0.255 to 0.268 inch, so a #2 bit will sit too shallow and cam out under torque.
5) Will these stainless machine screws rust in a damp or outdoor electrical install?
They are made from 18-8 stainless, the common chromium-nickel austenitic grade used for corrosion resistance in damp, washdown, and exterior-adjacent work. Metallics lists the intended use as electrical, plumbing, heating and air conditioning work, which is where that corrosion resistance matters most.
6) How are the JSRM85P screws packaged and what is the minimum order?
They ship in a jar of 100, and 100 is the minimum order quantity. Shipping weight on the jar is 1.78 lbs.
7) How strong are these 18-8 stainless machine screws compared to a grade 5 steel screw?
Tensile strength is listed at 80,000 psi minimum with a hardness of Rockwell B85 to B95. Metallics notes that tensile values for stainless screws are approximations, since there is no single performance standard for stainless machine screws. Grade 5 carbon steel runs higher in tensile, so where clamp load governs rather than corrosion, plated carbon steel is the better pick.
8) Can I use these for mounting devices, straps, and enclosures in an electrical rough-in?
That is what the SRM series is intended for, electrical, plumbing, heating and air conditioning work. A 1/4-20 x 1-1/4 inch length gives you enough thread to pass through a strut nut, a strap, or an enclosure wall and still engage fully. For blind tapped holes, allow for the full 1-1/4 inch of screw minus your material thickness.
