Product Description

This DIN 931 Hex Bolt M12x50, also known as a Half Thread Hex Bolt M12x50 or External Hex Screw M12x50, features a partial threading design with a 50mm shank length and M12 diameter. Constructed from grade 8.8 steel, it offers a tensile strength of 800 MPa and yield strength of 640 MPa. The external hex head accepts standard 19mm wrenches for secure fastening. With a half-threaded shaft for adjustable clamping range, it operates in temperatures from -50°C to +150°C and carries corrosion-resistant zinc plating. Widely used in structural engineering, machinery assembly, and automotive applications, this bolt excels in vibration-resistant connections but requires precise torque control (recommended 89Nm max). Compliant with ISO 4014 and DIN 931 standards, its dual-thread engagement zone enables both fixed and semi-floating joint configurations.
