Product Description

The M10x90 half thread bolt is a high-strength External hex bolt M10x90 designed for structural fastening in machinery, automotive, and construction applications. This Half threaded hex cap screw features a 10mm diameter, 90mm overall length, and a partially threaded shank (thread length typically 45-50mm) to optimize load distribution. Made from grade 8.8 steel with zinc plating, it operates reliably in temperatures from -30°C to 120°C. The external hex head enables 10mm wrench engagement for secure tightening up to 45 Nm torque. Its half-thread design combines shear resistance in the smooth shank section with tensile strength in the threaded portion. While offering excellent corrosion resistance and vibration durability, its partial threading requires precise installation alignment. Typical applications include engine mounts, structural frameworks, and heavy equipment assemblies requiring controlled clamping force.
