Product Description

The M6x55 half thread hex bolt is a partially threaded fastener designed with an external hexagonal head, featuring an M6 nominal diameter and 55mm total shank length. The half-threaded M6 bolt combines a smooth unthreaded shoulder (approx. 25mm) for precise alignment and a 30mm threaded section for secure clamping. Made typically from grade 8.8 carbon steel or A2/A4 stainless steel, it operates across -50°C to +250°C environments, suitable for machinery assembly, automotive frameworks, and structural applications requiring adjustable tension. The M6-55 external hex bolt offers high shear strength (up to 640MPa) and corrosion resistance with zinc-plated or hot-dip galvanized finishes. Its hex head accommodates 10mm wrenches for torque up to 15Nm. Advantages include vibration resistance and simplified installation, though limited thread engagement may restrict high-stress applications. Typical clamp thickness ranges 20-35mm depending on joint configuration.
