Product Description

The **M10x70 hex bolt**, also known as a **Half thread external hex bolt**, is a mechanical fastener designed with a hexagonal head (M10 hex head bolt) for tool engagement. It features a partially threaded shank (thread length approximately 35mm) and a smooth unthreaded shoulder, offering balanced grip strength and alignment in assemblies. Constructed from high-grade carbon steel or stainless steel (AISI 304/316), it complies with DIN 931 standards, with a tensile strength of 8.8-12.9 grade, nominal torque of 42-58 Nm, and corrosion-resistant zinc-plated or hot-dip galvanized finish. Ideal for automotive, construction, and heavy machinery industries, this bolt excels in high-vibration environments due to its secure hexagonal drive and partial threading. Limitations include limited adjustability in fully threaded applications. Operates reliably in temperatures from -30°C to 120°C and humidity up to 95% non-condensing. Typical installation requires M10 nuts and 17mm wrench size.
