http://www.smartbolts.com/fundamentals/ WebbThe ultimate or tensile stress is sometimes designed to, but we do not know when this acceptable or not. Also, the ultimate stress is used in designing joints for alternating loads, ... For alloy socket screws, yield strength is 180 ksi until 1/2″ and 170 ksi for larger diameters. We use 85% of these values to approximate proof strength.

WebbThe “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-70 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a nimimum tensile strength of 700N/mm ² (MPa). We stock round bar from 10 mm ... WebbIn a partially or fully annealed condition, the tensile strength of the 8.8 Hex Bolt is around 420 Mpa for low carbon steel and 500 Mpa for medium carbon steel, its core hardness in terms of Rockwell lies between B71 – 95. The surface hardness of the 8.8 Metric Bolt can be increased through carburizing. green seattle cedar
