Metallics JSPMP141SS – Frequently Asked Questions
1) What size and thread is the Metallics JSPMP141SS machine screw?
It's a 4-40 screw, 1 inch long, with 40 threads per inch on a #4 diameter. Standard UNC machine screw thread, so it mates with a 4-40 tapped hole or a 4-40 nut.
2) Can I use these on a federally funded job with domestic sourcing requirements?
No. The JSPMP141SS is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. For a job with domestic content requirements you'll need a domestically sourced fastener instead.
3) What size Phillips driver do I need for these 4-40 pan head screws?
A #1 Phillips. The recess diameter is 0.115 in. with a gaging depth of 0.053 to 0.071 in., so a #2 bit will cam out and chew the recess on a screw this small.
4) Are these stainless screws okay for outdoor or damp locations?
They're 18-8 stainless, the common austenitic grade used where plated steel would rust, so damp interiors, exterior boxes and washdown areas are fine. For chloride exposure such as coastal or pool chemical environments, 316 stainless is the better choice.
5) Do these screws meet a dimensional spec I can put on a submittal?
Head and recess dimensions conform to ASME B18.6.3-2010, the US standard for inch-series machine screws, and the material is called out to SAE. Tensile is 80,000 psi minimum, with hardness reported as Rockwell BBS-B9S. Note that stainless machine screw strength figures are approximations; there is no single performance standard for them.
6) How are the Metallics 4-40 x 1 in. stainless screws packaged, and what is the minimum order?
They ship in a jar, with a minimum of 100 count. That's a bench or truck-stock quantity rather than a bulk box.
