Metallics JSPM104SS – Frequently Asked Questions
1) Do these screws meet dimensional spec for submittals on a government or federally funded job?
They are built to ASME B18.6.3-2010 dimensionally, with SAE as the material standard, and the line is flagged both ARRA compliant and Buy American compliant. Country of origin is listed as multiple, so if your contract requires a single named origin, confirm the origin on the lot you receive.
2) Are these 18-8 stainless machine screws OK for outdoor or damp-location mounting?
The screw is 18-8 stainless throughout, which is the austenitic grade normally specified for wet and outdoor service, so it holds up in damp locations and exterior enclosures far better than a zinc-plated steel screw. It also avoids the galvanic problem of plated steel in stainless or aluminum enclosures.
3) How much does a pan head slotted machine screw stand off the surface once installed?
Head height runs 0.112 to 0.125 in. with a head width of 0.407 to 0.425 in. That low, broad pan profile spreads the bearing load on sheet metal and plastic plates without the head sitting proud enough to interfere with a cover or faceplate.
4) How strong is an 18-8 stainless machine screw compared to a plated steel one?
Tensile strength is 80,000 psi minimum. Metallics notes that stainless machine screw strength values are approximations only, because there is no single performance standard for stainless machine screws. For structural or high-torque pull, a hardened alloy steel screw rates higher; for corrosion service at device-mounting loads, 80,000 psi is ample.
5) How are these 12-24 x 1-1/4 stainless screws packaged and what is the smallest quantity I can buy?
They ship in a jar of 100, and 100 count is the order minimum. Metallics lists the packed jar at 1.33 lbs and 3 x 3 x 2.7 in., so it drops into a van bin or a cart drawer without repacking. Other sizes and quantities are available by request.
6) Can I use these as device or cover screws, or do I need a different head style?
Pan head sits on the surface, so these work where the screw head is allowed to show or clamp a strap, bracket, or ground bar. They are not a flush fastener. If your plate or enclosure has a countersunk hole and the head must finish flat with the surface, you need a flat head machine screw in the same 12-24 x 1-1/4 size instead.
7) Is the JSPM104SS a machine screw or a self-tapping sheet metal screw?
It is a machine screw, Metallics SPM series, model JSPM104SS. Machine threads run the full length and need a tapped hole or a nut, they will not form their own thread in sheet metal. For blind sheet metal you want a self-tapping or sheet metal screw instead.
