Product Description

The M14x120 hex bolt, also known as M14 hex head bolt 120mm, is a fully threaded metric fastener compliant with DIN 933 M14-120 standard. This steel external hexagonal bolt features a 14mm nominal diameter and 120mm shaft length with complete ISO metric coarse threading. Designed for structural connections in machinery, automotive assemblies, and heavy equipment, it offers Grade 8.8 tensile strength (equivalent to 800MPa ultimate tensile strength) and typically receives zinc-plated corrosion protection. The hex head accepts 21mm wrenches, operating effectively within -20°C to 120°C temperature ranges. Key advantages include uniform load distribution through full-length threads and vibration-resistant engagement, though the extended length may require precise pre-drilling in thin materials. Its standardized DIN dimensions ensure compatibility with industrial components across European mechanical engineering applications.
