Product Description

The Flathead Cross M3x20 Screw, also known as the M3 Cross Head Machine Screw or Flat Cross Machine Screw M3, is a precision fastening component designed for industrial machinery and electronics assembly. Featuring an M3 thread diameter and 20mm length, this cross-recessed (Phillips) drive screw operates within a standard voltage-free mechanical environment, ideal for securing modules in automation systems, robotics, and compact devices. Constructed from hardened steel, it withstands temperatures from -30°C to 120°C, ensuring reliability in automotive, aerospace, and consumer electronics applications. Its flat cross head design enables secure tool engagement, reducing cam-out risk during high-torque installation. Advantages include corrosion resistance and compatibility with M3 threaded holes, though it requires matching screwdrivers for optimal installation.
