M16X40 allen bolt 8.8 , Iran

The steel Allen bolt grade 8.8 size M16X40, with a nominal diameter of 16 millimeters and a threaded length of 40 millimeters, has an ultimate tensile strength of approximately 800 MPa and a yield tensile strength of 640 MPa. Under static loading conditions, it can withstand a tensile force of about 100 to 110 kN, which is suitable for use in industrial and mechanical structures with a safety factor of 3. The approximate weight of each bolt, considering the steel density of 7.85 g/cm³, is around 98 to 102 grams.

In terms of wear resistance and tightening torque, this grade 8.8 Allen bolt can endure tightening torques of 210 to 230 Nm under dry conditions. The Working Load Limit WLL for safe operation is estimated at about 30 to 35 kN. The internal hexagon Allen design increases precision in tightening and reduces the risk of thread stripping under repeated loading. These features make it highly suitable for heavy machinery joints and high-stress steel structures.You can order and buy M16X40 allen bolt 8.8 from Iran by contacting us through whatsaap and email.
