Product Description

The M20x170 hex bolt is a half-thread hex bolt featuring an external hexagon head and a partially threaded shank, designed for applications requiring robust fastening with partial grip adjustment. With a nominal diameter of 20mm, full length of 170mm, and threaded portion spanning 85mm, this external hexagon bolt is typically constructed from grade 8.8 carbon steel, zinc-plated for corrosion resistance. It operates in temperatures from -30°C to 120°C, withstands tensile loads up to 800 MPa, and supports torque values around 400 Nm. Widely used in construction, machinery, and automotive assemblies, its half-thread design enables flexibility in joint alignment while maintaining clamping force. Key advantages include high mechanical strength and simplified installation, though its partial threading limits full shank engagement in critical shear-load scenarios.
