Stainless hex cap screws have a washer face, a radius under the head, and a chamfered point. Available in 18-8 and 316 stainless steel, RC Fasteners & Components’ stainless hex cap screws are made from the austenitic alloys described here:

18-8 Stainless Cap Screws

Offered in fully threaded or normal 18-8 stainless cap screws. They are made from one of the following austenitic alloys: 303, 303Se, 304, or XM7, all of which are characterized as having chromium content of 17-19% and nickel content of 8-10%. 18-8 stainless is used in products that require general atmospheric corrosion resistance.

316 Stainless Cap Screws

316 or A4 stainless hex cap screws are made from an austenitic alloy which differs from 18-8 by its molybdenum content (2-3%) and a higher nickel content (10-14%). This molybdenum content gives 316 stainless even greater corrosion resistance than 18-8, as well as superior strength at high temperatures.
