The steel Allen bolt grade 8.8 size M16 with a length of 70 mm has an approximate weight of 0.16 kg and is manufactured according to DIN 912 and ISO 4762 standards. With a tensile strength of 800 MPa and a yield strength of 640 MPa, it is designed for mechanical joints under heavy loading. The 70 mm length allows deeper thread engagement, increasing connection safety and stability under vibration and variable loads.

The industrial application of the 8.8 M16x70 Allen bolt is common in machinery manufacturing, hydraulic equipment, metal structures, and engine assemblies. With a 2 mm pitch and an effective thread cross section of 157 mm², it can withstand axial loads exceeding 100 kN. Its excellent torsional resistance makes it suitable for steel chassis and heavy machine frames.

In oil and gas industries as well as mining equipment, the 8.8 M16x70 Allen bolt is widely used due to its high strength and surface hardness of 22 to 34 HRC. Surface treatments such as galvanization and phosphating enhance corrosion and wear resistance, increasing the service life of the connection. These properties ensure reliable and safe performance in humid, corrosive, and cyclic load environments.
