Metallics JPMP4 – Frequently Asked Questions
1) Will the Metallics JPMP4 8-32 screw work for mounting device plates and receptacles in an electrical box?
8-32 is the standard machine screw thread used for device and cover plate mounting, and the JPMP4 is an 8-32 x 1/4 in. pan head Phillips machine screw in zinc plated steel. At 1/4 inch long it is short, so it suits shallow tapped holes like plate and strap mounting rather than anything needing depth through a thick plate stack. Metallics lists the series for the electrical, plumbing, heating and air conditioning trades.
2) Will zinc plated steel screws hold up outdoors or in a wet location?
The JPMP4 has a zinc finish over carbon steel, which is a dry indoor plating. For damp, outdoor or washdown work use a stainless machine screw of the same 8-32 x 1/4 size instead. Note that tensile values quoted for stainless machine screws are approximations only, since there is no single performance standard for them.
3) Do these Metallics screws meet Buy American or ARRA requirements for a government job?
No. The JPMP4 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your spec carries a domestic sourcing clause, this part will not satisfy it.
4) What thread pitch is 8-32, and will it thread into my existing tapped hole?
32 threads per inch, the standard coarse pitch for a #8 machine screw. It threads into any 8-32 tapped hole or 8-32 nut, including the tapped ears on standard steel device boxes and mounting straps. It will not fit a #6-32 hole, which is the other common size found on electrical devices.
5) What size Phillips driver do I need for these 8-32 pan head screws?
A #2 Phillips bit. The recess diameter is 0.175 in. with a recess penetration gaging depth of 0.071 to 0.097 in., so a #1 will cam out and a #3 will not seat.
6) How much does the pan head stand off the surface, and how wide is it?
Head height runs 0.105 to 0.115 in. and head width 0.306 to 0.322 in., per ASME B18.6.3-2010. That low rounded profile is why pan head is used on cover plates and brackets where a flush countersink is not prepped in the part.
7) How are the Metallics JPMP4 machine screws packaged and what is the minimum order?
They ship in a jar of 100, which is the order minimum. Other sizes and quantities are available by request.
8) Are these 8-32 screws strong enough for a mounting bracket, and how hard is the steel?
Tensile strength is 60,000 psi minimum with hardness at Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial machine screw strength, fine for device, bracket and enclosure mounting, not a substitute for a graded cap screw in a structural or high load joint.
