Product Description

M4x4 electronic screws, also known as M4*4 PCB screws or M4x4mm small fasteners, are precision-engineered components designed for secure circuit board mounting in compact electronics. These miniature fasteners feature 4mm thread length with 4mm diameter, optimized for space-constrained PCB installations. Compatible with standard M4 threaded inserts and spacers, they operate effectively within industrial temperature ranges (-40°C to +125°C) and various voltage environments. Widely used in industrial automation, telecom equipment, and IoT devices, these screws provide reliable electrical grounding and vibration resistance. The zinc-plated steel construction ensures corrosion resistance, while the reduced head profile enables flush mounting. Though lacking complex interfaces or power requirements, their compact design requires specialized drivers for installation. Typical applications include securing microcontrollers, sensors, and power modules in dense PCB layouts.
