Metallics JSPMP21SS316 – Frequently Asked Questions
1) What size and thread is the Metallics JSPMP21SS316 machine screw?
It's a 10-24 x 1/2 inch pan head Phillips machine screw. 10-24 means a #10 diameter with 24 threads per inch, the coarse UNC machine screw thread, so it mates with a 10-24 tapped hole or a 10-24 nut. Overall shank length is 1/2 inch, which limits you to thin material or shallow tapped holes.
2) Is this screw stainless steel, and which grade?
316 stainless, not 18-8/304. The 316 alloy carries molybdenum, which is why it is the one specified for coastal, marine, wastewater, and chemical exposure where chlorides attack lesser stainless. If your spec just says "stainless," 316 meets it; if the spec calls for 316 specifically, a 304 screw does not.
3) How many screws come in the jar?
100 pieces per jar, packed in a jar rather than a box or bag, so it stays sorted on a service truck or bench. The JSPMP21SS316 is sold as that jar, not loose by the piece.
4) Can I use a 10-24 pan head machine screw to mount devices in an electrical box?
That's the common use for it. 10-24 is the standard thread on steel outlet and device box ground and mounting holes, and a pan head Phillips sits flat against a plate or strap. In 316 stainless it is the version for wet, outdoor, or corrosive locations. Only 1/2 inch of length, though, so for stacking a mud ring plus bracket you may need a longer screw.
5) Will a 316 stainless screw hold up outdoors and near salt air?
Yes, that's the reason to pick this one. 316 stainless is the grade used for marine and coastal exposure because it resists chloride pitting better than 304 or plated steel. For exterior enclosures, dock and pier work, car washes, and treatment plants, a zinc-plated screw will bleed rust long before a 316 one does.
6) What driver do I need for the JSPMP21SS316?
A Phillips bit. It is a pan head Phillips machine screw, so a #2 Phillips suits a #10 head. Stainless galls easily, so drive it at moderate speed and do not over-torque it in a tapped aluminum hole.
