Product Description

The M6x65 hex bolt is a Metric external hex bolt manufactured according to DIN 931 M6-65 standard, designed for precision fastening in mechanical assemblies. With a 6mm nominal diameter and 65mm shaft length, it features a full-threaded design for uniform load distribution. Constructed from grade 8.8 steel with optional zinc-plated or stainless steel finishes, it operates effectively within -50°C to +150°C temperatures and sustains clamping forces up to 15.6kN. This fastener is widely applied in automotive, machinery, and structural engineering due to its compliance with ISO 4014 standards and corrosion-resistant variants. While offering high tensile strength and vibration resistance, installation requires calibrated torque tools to prevent overtightening. The hex head design enables 10mm wrench compatibility, ensuring secure industrial-grade fastening across diverse environments.
