Product Description

The Half Thread Hex Bolt M14x50 (External Hexagon Bolt M14x50) features a partial threading design with a 14mm diameter and 50mm nominal length, combining a threaded segment for secure fastening and an unthreaded shank for alignment. This M14-50 Partial Thread Hex Bolt meets ISO 4014/DIN 933 standards, crafted in grade 8.8 carbon steel or A2/A4 stainless steel, offering tensile strengths up to 800MPa. Its external hexagon head enables tool engagement via 21mm AF wrenches. Applications span construction, automotive assembly, and industrial machinery, operating in environments from -30°C to +250°C. Surface coatings include galvanized, zinc-plated, or dacromet options for corrosion resistance. Advantages include reduced material usage from partial threading and vibration resistance, though precise torque control is required to prevent joint slippage.
