Metallics JSPMP15SS – Frequently Asked Questions
1) Do these Metallics screws meet a dimensional spec I can put on a submittal?
Head, drive, and thread dimensions conform to ASME B18.6.3-2010, the standard for inch-series machine screws, with material called out to SAE. Tensile strength is listed at 80,000 psi minimum and hardness at Rockwell BBS-B9S. Note that stainless machine screw tensile values are approximations; there is no single performance standard for stainless machine screws.
2) Are these Buy American or ARRA compliant for a government job?
No. The JSPMP15SS is not Buy American compliant and is not ARRA compliant. Country of origin is listed as multiple. If your project carries domestic sourcing requirements, these will not satisfy them.
3) Are these stainless machine screws OK outdoors or in a damp location?
The screws are 18-8 stainless, which is the common austenitic grade used where corrosion resistance matters, so they hold up far better than plated steel in damp, exterior, or washdown locations. For heavy chloride exposure (coastal or pool chemical environments) a 316 stainless fastener is the usual step up.
4) What screwdriver or bit do I need for these Metallics pan head Phillips screws?
A #2 Phillips bit. The recess is a Phillips drive with a 0.175 in. recess diameter and a gaging depth of 0.071 to 0.097 in., so a #2 seats properly without camming out. A #1 will spin in the recess and a #3 will not seat.
5) How much does the pan head sit up off the surface, and will it clear a cover plate?
Head height runs 0.105 to 0.115 in. with a head width of 0.306 to 0.322 in. That is a low rounded profile with a flat bearing face, so it sits proud of the surface by roughly a tenth of an inch. If you need the head flush with the material, a flat head screw in a countersunk hole is what you want instead.
6) How are these sold, and what is the minimum I have to buy?
They ship in a jar of 100, which is also the order minimum. Shipping weight for the jar is listed at 0.44 lbs. There is no option to buy a single screw.
7) Is a machine screw the right choice, or should I be using a sheet metal screw?
A machine screw like this one has a uniform straight thread and a blunt end, so it needs a tapped hole or a nut. It will not cut its own thread into sheet metal or drywall. Use it where the mating part is already threaded (device boxes, enclosures, tapped brackets) or pair it with an 8-32 nut. If you are fastening into unthreaded sheet metal, a self-tapping sheet metal screw is the correct part.
8) Will a 1/2 inch length be long enough for stacking a cover plate and gasket?
Half an inch of overall length leaves limited thread once you stack material, so figure the combined thickness of what you are clamping plus enough engagement in the tapped hole. For deeper stacks, Metallics offers the same 8-32 pan head Phillips stainless screw in other lengths by request.
