Product Description

The M14x80 hex bolt is a high-strength metric hex bolt designed for robust mechanical applications, featuring an 80mm shank length and M14 thread diameter. This M14 80mm hex bolt is typically manufactured from grade 8.8 carbon steel or A2/A4 stainless steel, offering a tensile strength of 800 MPa (grade 8.8) and corrosion resistance (stainless variants). It operates reliably in temperatures ranging from -50°C to +300°C, depending on material, and complies with DIN 933/ISO 4014 standards. Ideal for automotive, machinery, and structural assemblies, the metric hex bolts M14x80 provide secure fastening with a 21mm hex head requiring a 14mm wrench. Advantages include high load capacity and durability, though precise torque calibration is critical to avoid over-tightening. Surface coatings like zinc plating or hot-dip galvanizing enhance environmental resistance. Commonly used in industrial equipment, construction frameworks, and heavy-duty fixtures, these bolts ensure stability under dynamic stresses.
