Metallics JSRM05 8-32 x 1-3/4 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

18-8 stainless is the austenitic 300-series alloy used where plated steel would rust, so it suits wet locations, exterior boxes, coastal jobs, pool and car wash equipment, and food plants. Hardness runs Rockwell B85-B95 and minimum tensile strength is 80,000 psi. Keep in mind stainless is not a graded-strength fastener the way a hardened steel screw is, so use it where corrosion is the problem rather than where high clamp load is.

No, and Metallics says so directly: tensile values for stainless screws are approximations, since there is no single performance standard for stainless machine screws. The published figure is 80,000 psi minimum against the SAE material standard. Use them for device mounting, enclosure covers, brackets, and general MRO work, not for a connection where a certified grade is called out on the drawing.

The JSRM05 ships as a 100-count jar, and 100 is the order minimum. If you are stocking a van or a maintenance crib, that is one jar per order increment rather than loose each-picks.

Metallics lists the JSRM05 as both ARRA compliant and Buy American compliant, with country of origin China. On federally funded work those two flags are what the submittal reviewer looks for, so cite them against the spec section governing your project.

A jar comes in at 0.96 lbs. Handy if you are building out a parts order against a freight threshold or loading a service truck's fastener drawer.
