Product Description

The M1.4 Micro Screw 4mm is a metric precision fastener designed for ultra-compact applications, featuring a thread diameter of 1.4mm, a shank length of 4mm, and a compact 2.5mm head height. This Metric Screw M1.4x4 excels in confined spaces requiring high mechanical stability, with a corrosion-resistant stainless steel construction supporting operating temperatures from -20°C to 120°C. The 2.5mm Head Precision Screw delivers exceptional torque transmission efficiency despite its miniature dimensions, optimized for electronics assembly, medical devices, and micro-optics. Its ultra-low profile design minimizes component protrusion while maintaining a tensile strength of 400MPa. Installation requires a 1.5mm flat-head driver due to the precision-machined head geometry. Common limitations include increased vulnerability to over-tightening and compatibility only with pre-tapped M1.4 metric threading. The screw achieves 0.01mm dimensional tolerance for critical alignment applications.
