Product Description

The M16*200 hex bolt is a high-strength half-thread external hex bolt designed for robust mechanical fastening applications. Featuring a 200mm overall length with a partially threaded shank (thread length approximately 100mm) and an M16 nominal diameter, this external hex bolt 200mm variant offers a hexagonal head for tool engagement using 24mm wrenches. Manufactured from grade 8.8 carbon steel or A2-70 stainless steel options, it provides tensile strength up to 800 MPa (carbon steel) and corrosion resistance in environments with up to 95% humidity. Suitable for structural engineering, heavy machinery, and automotive assemblies, the half thread M16 bolt configuration allows dual functionality: threaded engagement at one end and smooth shaft surface for precision alignment. Operating temperature ranges from -50°C to +150°C (carbon steel) or -40°C to +210°C (stainless variant). Key advantages include vibration resistance through the full hexagon drive interface and reduced material stress from partial threading, though installation requires precise torque control (recommended 210 N·m for steel) to prevent under/over-tightening in critical load-bearing applications.
