Metallics JSRM190P – Frequently Asked Questions
1) Are these stainless screws OK for outdoor or damp-location use?
18-8 stainless is the material, which is the common austenitic grade used for wet and outdoor fastening and will not rust out the way a plated steel screw does. For salt spray or coastal exposure, 316 is the step up.
2) Is a machine screw the right choice, or do I need a sheet metal or self-tapping screw?
A machine screw like this 10-32 has a uniform, blunt-ended thread meant to go into an already-tapped hole or a nut, not to cut its own. If the hole in your box, strap or bracket is pre-tapped 10-32, this is the right fastener. If you are driving into untapped sheet metal, use a sheet metal or self-drilling screw instead.
3) What size Phillips bit do I need for these Metallics 10-32 round head screws?
A #2 Phillips. The recess is sized at 0.182 to 0.195 inch diameter with a 0.093 to 0.119 inch depth, so a #1 bit will cam out and a #3 will not seat.
4) How much of a head does a round head 10-32 screw leave sitting on the surface?
The round head measures 0.334 to 0.359 inch across and stands 0.123 to 0.137 inch above the surface. It is a non-countersunk head, so it sits proud on the plate or strap rather than pulling flush. If you need the head to disappear into a chamfered hole, a flat head machine screw is the one to order instead.
5) How are Metallics JSRM190P machine screws packaged and what is the minimum I can buy?
They ship in a jar of 100, and 100 count is the order minimum. Figure roughly 2.21 lbs for the jar.
6) What is the tensile strength of these 18-8 stainless machine screws, and can I use them structurally?
80,000 psi minimum, with a hardness of Rockwell B85 to B95. Metallics notes that tensile values for stainless machine screws are approximations, since there is no single performance standard for them. That is fine for mounting devices, straps, boxes and fixtures; it is not a substitute for a graded structural bolt.
7) Do these screws qualify for a Buy American or ARRA job?
The JSRM190P is flagged compliant for both ARRA and Buy American in Metallics' data, while country of origin is listed as China. On a federally funded spec where the contracting officer requires domestic melt and manufacture, confirm which clause your job is written to before you submit them.
