Metallics JSPMP29SS – Frequently Asked Questions

1) How many 1/4-20 x 3/8 in. Metallics pan head machine screws come in a jar, and can I buy fewer?
The JSPMP29SS ships as a jar of 100 screws, and the jar is the order minimum, so 100 pieces is the smallest quantity. The filled jar weighs 1.01 lbs.
2) What size Phillips driver do I need for these 1/4-20 pan head screws?
Use a #3 Phillips bit. The recess diameter is 0.274 in. with a gaging depth of 0.118 to 0.144 in., so a #2 bit will sit shallow in the recess and cam out when you torque it down.
3) Can I use these Metallics screws on a Buy American or ARRA-funded project?
No. The JSPMP29SS is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. For federally funded work with domestic sourcing requirements you will need a domestically produced fastener instead.
4) Will 18-8 stainless machine screws hold up outdoors or in a damp mechanical room?
18-8 stainless is the standard austenitic grade used where plated steel would rust, so these are a reasonable choice for exterior enclosures, wet locations, and damp mechanical spaces. One caution: pairing stainless with dissimilar metals in a wet environment invites galvanic corrosion, so match the hardware you are threading into where you can.
5) Do these screws meet a dimensional standard I can put on a submittal?
The SPMP series pan head screws are made to ASME B18.6.3-2010, the dimensional standard for inch-series machine screws, with material to SAE. Tensile strength is listed at 80,000 psi minimum, though Metallics notes stainless tensile figures are approximations since there is no single performance standard for stainless machine screws.
6) What trades actually use 1/4-20 x 3/8 pan head stainless machine screws?
Metallics lists these for the electrical, plumbing, and HVAC trades. In practice that is panel and enclosure hardware, strut fittings and brackets, equipment covers, and tapped-hole fastening where a rust-free screw is wanted. They are machine screws, so they need a tapped hole or a nut, they will not form their own thread in sheet metal.
7) Can I get this Metallics pan head screw in other lengths or a different jar count?
Yes, the SPMP pan head Phillips line runs in other sizes and quantities by request beyond the 1/4-20 x 3/8 in. 100-count jar.
