Product Description

The M6x45 half-thread bolt, designed with an external hex head M6 screw configuration, features a partial thread hex bolt 45mm length combining 25mm threaded section and 20mm smooth shank for controlled clamping force distribution. Made of grade 8.8 carbon steel with zinc plating, it operates in -30°C to +150°C environments, offering 800 MPa tensile strength and corrosion resistance. Ideal for automotive, machinery, and structural applications, its 10mm hex head accepts standard wrenches for 20 Nm maximum torque. The partial threading reduces material contact points while maintaining joint integrity, though limits adjustment range compared to full-thread variants. This fastener excels in vibration-prone assemblies but requires precise length matching due to its fixed thread-to-shank ratio.
