Metallics JSPMP102SS – Frequently Asked Questions
1) Will a 1/4-20 pan head screw thread into a standard 1/4-20 tapped box or strut nut?
Yes. The JSPMP102SS is cut 1/4-20, meaning a 1/4 inch nominal diameter at 20 threads per inch, which is the standard coarse 1/4 inch machine thread used in tapped enclosure bosses, channel nuts and 1/4-20 nuts. Dimensions follow ASME B18.6.3-2010, so head and thread geometry match any other conforming 1/4-20 pan head.
2) Can I use these stainless machine screws outdoors or in a wet location?
18-8 stainless is the usual choice for damp and outdoor electrical work: exterior fixture mounting, wet-location boxes, coastal and washdown areas where a plated steel screw rusts in place and seizes. These are 18-8 stainless through the body, not a coating, so cut ends and scratches do not open a corrosion path.
3) Do I get one screw or a box when I order the Metallics JSPMP102SS?
These ship 100 to a jar, and 100 count is the order minimum, so the smallest purchase is a full jar of 1/4-20 x 1-1/4 inch pan head screws. The jar weighs 1.78 lbs. Other sizes and quantities can be requested.
4) What size driver do I need for the Metallics JSPMP102SS pan head Phillips machine screw?
A #3 Phillips driver. The recess diameter is 0.274 inch with a gaging depth of 0.118 to 0.144 inch, so a #2 bit will cam out and chew the recess on a 1/4-20 screw. Bring a #3.
5) Are these Metallics stainless screws strong enough for a structural or load-bearing connection?
No, treat them as a general-purpose fastener. Tensile strength is listed at 80,000 psi minimum with Rockwell BBS-B9S hardness, and stainless machine screws have no single governing performance standard, so the value is an approximation rather than a graded rating. For a rated structural or load-path connection, specify a graded steel bolt instead.
6) Do these screws qualify for a Buy American or ARRA-funded project?
The JSPMP102SS is flagged ARRA compliant and Buy American compliant, with country of origin China. If your contract language requires domestic melt and manufacture rather than the Buy American compliance flag, verify against the specific clause on your project.
7) Is a pan head the right choice, or should I use a flat head for mounting a device in an enclosure?
Pan head sits proud of the surface on a flat bearing face, so it needs no countersink and is what you want for tapped bosses in boxes, strut nuts, and plate mounting where the hole is a plain drilled through-hole. Go to a flat head only if the hole is countersunk or the screw head must finish flush with the surface. The pan head here stands 0.162 to 0.175 inch above the work.
