Product Description

The M1.4 hex socket screws are precision fasteners with a cylindrical head design, engineered for compact spaces requiring secure fastening. These M1.4x4mm socket head screws feature a 1.4mm diameter and 4mm length, paired with a cylindrical head measuring 2.6mm in diameter and 1mm height. Designed to be driven by a 0.7mm Allen key, they provide reliable torque transmission and resistance to cam-out. Manufactured from grade 12.9 alloy steel with zinc-plated or black oxide coatings, these screws operate effectively in temperatures ranging from -30°C to 120°C. Ideal for electronics, precision machinery, and micro-assembly applications, their key advantages include space-saving design and high shear strength, though their small size demands careful handling to avoid tool slippage or cross-threading during installation. Proper torque settings (0.15-0.2 Nm) must be maintained to prevent thread stripping.
