Product Description

The M12x80 half thread bolt, also known as the External hex bolt M12x80, is a DIN 931 compliant fastener designed for robust mechanical applications. Featuring a 12mm diameter, 80mm total length, and a partially threaded shank (typically 40mm thread length), it combines secure grip and easy alignment. Constructed from high-grade steel or stainless steel with galvanized or zinc-plated coating, it offers tensile strength up to 800 MPa and torque ratings of 90-110 Nm. Suitable for environments ranging from -50°C to +250°C, this bolt is widely used in automotive, machinery, and structural industries. Its external hex design enables tool compatibility with standard wrenches, though installation requires adequate lateral space. Advantages include corrosion resistance and high load capacity, while limited accessibility in tight spaces may pose a minor drawback.
