Product Description

The M14x90 half thread external hexagonal bolt is a heavy-duty fastener designed for robust mechanical connections. This External hex bolt M14x90 features a partial threading (half-thread design) spanning 45mm, leaving a smooth 45mm shank, and has a total length of 90mm with an M14 diameter. Constructed from high-grade steel (Grade 8.8), it includes a zinc-plated finish for corrosion resistance. The external hexagon head requires a 21mm wrench for installation. Ideal for industrial applications such as machinery assembly, construction frameworks, and automotive systems, this Half thread hex screw M14x90 enables secure clamping with its partially threaded structure, allowing adjustable tension and shear resistance. Operating temperatures range from -30°C to 120°C. Advantages include high tensile strength and ease of alignment, while limitations involve potential galvanic corrosion in harsh environments without additional coating. Not compatible with low-clearance spaces due to its protruding hex head design.
