Product Description

The M10x85 half thread bolt, compliant with DIN 931 M10x85 bolt standards, is a partially threaded hex bolt designed for high-strength fastening applications. Featuring a 10 mm diameter, 85 mm total length, and a threaded segment spanning approximately 55 mm, it combines a smooth shank (30 mm unthreaded) with ISO metric coarse thread (pitch 1.5 mm). The hexagonal head (17 mm across flats, 6.4 mm height) ensures secure wrench engagement. Manufactured from grade 8.8 carbon steel or optional stainless steel (A2/A4), it offers a tensile strength of 800 MPa and yield strength of 640 MPa. Surface treatments include hot-dip galvanizing (45-55 µm) or plain finish. Operating temperature ranges from -50°C to +300°C. Widely used in machinery, automotive, and structural engineering, its hybrid threaded/unthreaded design balances shear resistance and clamping force while reducing thread wear. Key advantages include corrosion resistance and vibration tolerance, though partial threading limits adjustability in some configurations. Complies with DIN 931 dimensions for full compatibility with standard nuts and tools.
