Product Description

The M14x70 Half Thread Hex Bolt, also known as the External Hex Bolt M14-70 or 14mm Hex Half Thread Bolt, features a 14mm diameter shaft and 70mm total length with a partially threaded section. Designed for robust mechanical fastening, it operates under ambient temperatures ranging from -50°C to +250°C. Its external hex head allows torque application via standard wrenches, ideal for machinery assembly, automotive frameworks, and structural engineering applications. The half-thread design balances shear resistance and clamping force, enhancing vibration resistance in high-stress environments. Constructed from grade 8.8 steel with optional zinc-plated corrosion protection, this bolt excels in durability but requires precise torque calibration to avoid overtightening. Compatible with 14mm nuts and washers, it supports axial loads up to 20kN. Primary limitations include potential thread galling in aluminum substrates and reduced effectiveness in continuous submersion scenarios.
