The material has a minimum yield strength of 205 MPa and a minimum tensile strength of 515 MPa. These values make fasteners suitable for high temperature and high pressure applications as well. SS 316 Nut Bolt price lists vary by supplier, fastener type and delivery location. One of the reasons for the better mechanical and physical properties of Type 316 stainless steel fasteners is the composition of the alloy. The alloy of 316 stainless steel screws is basically composed of three key elements – chromium, nickel and molybdenum.
A hex head bolt is a cylindrical fastener with a one-piece head on one end and an external thread on the other, designed to be inserted into a hole in an assembled part and mate with an internally threaded block called a nut, turned to tighten or loosen Unscrew the bolt. Alloy 316 is a molybdenum-containing austenitic stainless steel containing 18% chromium, 8% nickel, and 2-3% molybdenum.
