Product Description

The M5x12 hex flange screws, also known as hexagonal flange head bolts M5, are metric fasteners featuring a 5mm nominal diameter and 12mm shank length. Designed with an integrated hexagonal flange head, these screws eliminate the need for separate washers, providing a secure, vibration-resistant connection in tight spaces. The metric hex flange screw 12mm variant typically employs ISO 4762 or DIN 6921 standards, with material options including stainless steel (A2/A4) or carbon steel (grade 8.8/10.9) and zinc-plated/plain finishes. Ideal for machinery assembly, automotive components, and electrical enclosures, they offer enhanced load distribution through the flange base. Key advantages include improved torque transmission via the hexagonal head and space-efficient installation, though limited accessibility in deep recesses may require specialized tools. These screws operate effectively within -50°C to +150°C environments depending on material, with typical tensile strengths ranging from 800 MPa (stainless) to 1000 MPa (carbon steel).
