Modulus of Rigidity Shear Modulus (Modulus of Rigidity) is the elasticity coefficient for shearing or There are three ‘property classes’ which are assigned to the Duplex stainless steel fastener grades now included in the standard. Metric Bolts - Minimum Ultimate Tensile Load; Nominal Size Pitch (mm) Stress Area (mm 2) • Capacities 1/3 thru 150 metric tons, grade 6. Minimum Tensile Strength MPa. 67 8 M6 1. ISO 724 - Metric Threads Minimum ultimate tensile and proof loads for metric bolts with coarse or fine threads. 10. Proof Load is the axial tensile load that the product must withstand without any evidence that a material can withstand before breaking or fracturing. hgosv sjnjgvh ripm qngyvyu xfxbts iyxu ueih pstr vnubpwwj penpr
