Product Description

The M8x80 metric hex bolts are high-strength external hex bolts designed for robust mechanical connections, featuring an 8mm diameter and 80mm length with metric coarse threading. These metric M8x80 hex head bolts comply with ISO 4014/DIN 931 standards, constructed from grade 8.8 carbon steel or A2/A4 stainless steel options, and include hot-dip galvanized or zinc-plated finishes for corrosion resistance. Ideal for automotive, machinery, and structural applications, they operate reliably in temperatures from -50°C to +150°C, supporting tensile loads up to 800 MPa. The external hex bolts M8 80mm allow secure wrench engagement for high-torque installations, though their extended length may require ample clearance space. Advantages include exceptional shear strength and environmental durability, while the primary limitation involves compatibility with specific thickness ranges in assembly scenarios. These bolts are widely utilized in heavy-duty industrial equipment, construction frameworks, and precision engineering systems.
