Product Description

The M6x70 hex bolts are metric hexagon bolts featuring an external hex head M6 design with a nominal diameter of 6 mm and a length of 70 mm. These bolts comply with standard metric dimensions, typically adhering to DIN 931 or ISO 4014 specifications. Constructed from high-strength steel or stainless steel (e.g., A2/A4 grades), they offer a tensile strength range of 800-1000 MPa, suitable for heavy-duty industrial applications. With a hexagonal head height of 4 mm and a wrench size of 10 mm, these bolts provide reliable torque transmission and are commonly used in machinery, automotive assembly, and structural frameworks. Surface treatments like zinc plating or galvanization enhance corrosion resistance, supporting operation in temperatures ranging from -50°C to +150°C. Key advantages include high clamping force and ease of installation with standard tools, though the external hex head requires adequate clearance for wrench access. Not applicable for electronic parameters like voltage or communication interfaces.
