Product Description

The Half thread hex bolt M8x90, commonly referred to as the External hex head bolt M8x90, is a precision fastening component with a nominal diameter of 8 mm, a total length of 90 mm, and a partially threaded shank. Designed for applications requiring adjustable grip length, this M8x90 half thread hex bolt typically utilizes carbon steel or stainless steel (Grade 8.8 or A2-70), featuring a zinc-plated or galvanized surface for corrosion resistance. It operates within a temperature range of -50°C to +150°C, suitable for industrial machinery, automotive assemblies, and structural frameworks. The external hex head enables high torque application via standard 13 mm wrench, while the half-thread design balances shear strength and adjustability. Key advantages include durability, ease of installation, and compatibility with dynamic loads, though partial threading may limit engagement in thin materials. No integrated electronics, power systems, or communication interfaces are incorporated in this purely mechanical fastener.
