Metallics JSPMP100SS – Frequently Asked Questions

1) Will a 1/4-20 pan head machine screw thread into a 1/4-20 tapped box or strut nut?
Yes. The Metallics JSPMP100SS is a 1/4-20 machine screw, 20 threads per inch, so it mates with any 1/4-20 tapped hole or nut, including 1/4-20 strut nuts and tapped enclosure holes. Thread dimensions follow ASME B18.6.3-2010, the standard dimensional spec for inch machine screws.
2) Are these stainless screws OK for outdoor or damp-location electrical work?
The screws are 18-8 stainless, the common austenitic grade used for corrosion resistance in wet and outdoor locations, so they hold up where plated steel would rust and streak. For heavy chloride exposure such as coastal or pool chemical environments, 316 stainless is the step up.
3) Do these Metallics stainless screws meet Buy American or ARRA requirements for a federal job?
No. The JSPMP100SS is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your project carries a domestic sourcing clause, these will not satisfy it.
4) Is a machine screw the right fastener here, or do I need a self-tapping screw?
A machine screw like this one has a uniform straight thread and no point, so it needs a pre-tapped 1/4-20 hole or a mating nut. If you are driving into sheet metal or an untapped hole, you want a self-drilling or self-tapping screw instead. For mounting into tapped enclosure bosses, strut nuts, or through-bolting with a 1/4-20 nut, the machine screw is correct.
5) What size Phillips driver do I need for these 1/4-20 pan head screws?
Use a #3 Phillips bit. The recess is 0.274 in. in diameter with a gaging depth of 0.118 to 0.144 in., so a #2 bit will cam out and chew the recess under torque.
6) How strong are 18-8 stainless machine screws compared to a grade 5 steel screw?
Tensile strength on these is listed at 80,000 psi minimum, with hardness in the Rockwell B range. That sits below a grade 5 steel fastener, so for a structural or high-torque clamp load, plated steel is the better choice. Stainless tensile values for machine screws are approximations, since there is no single performance standard for them.
7) How are these 1/4-20 x 3/4 in. screws packaged, and what is the smallest quantity I can buy?
They come in a jar of 100, and 100 count is the order minimum. Handy for a service van or a shop bin rather than a single-piece pull.
