Product Description

The Half thread M8x65 hex bolt is a high-precision fastening component designed for industrial applications. This M8x65 external hex bolt features a partially threaded shank with 65mm total length, a 13mm hexagonal head, and an unthreaded shoulder section spanning approximately 32.5mm. Manufactured from grade 8.8 carbon steel with zinc-plated finish, it offers 640-800 MPa tensile strength and 10.9 MPa proof load capacity. The external hexagonal bolt M8x65 operates within -20°C to +120°C temperature range, making it suitable for automotive assembly, machinery manufacturing, and structural engineering applications. Its corrosion-resistant coating ensures durability in moderate environments while the half-thread design provides simultaneous clamping and alignment functions. The combination of partial threading and standard M8x1.25 pitch enables secure fastening in vibration-prone environments, though full-thread engagement isn't achievable. Compatible with standard 13mm wrench sizes, this fastener requires 22-24 Nm tightening torque for optimal performance.
