The 316 alloy is a molybdenum-bearing austenitic stainless steel that contains 18% chromium, 8% nickel, and 2-3% molybdenum. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than the 304 alloy, which is especially true in pitting and crevice corrosion within chloride environments. In addition, Alloy 316 provides excellent elevated temperature tensile and stress rupture strengths, as well as outstanding weldability.

A Counter Sunk Cap Screw is a type of screw that’s designed to rest flush with the object or surface in which it’s inserted. They are called “countersunk screws” because they “sink” into objects and surfaces. They feature a flat head that tapers along the shaft.
