M3 screws

M3 screws are widely used in light construction applications where precision and smaller fastenings are needed. These screws are commonly selected for metal-to-metal or metal-to-plastic connections in installations such as electrical panels, ducting, and mechanical assemblies. Builders also use M3 screws for tasks involving sheet materials and engineered components where size and uniformity are critical.

The range of M3 screws includes pan head, countersunk, and button head types, each suited to different materials and finish requirements. Most come in machine-threaded variants for use with tapped holes or matching nuts. Stainless steel and zinc-plated options are common, offering varying resistance to corrosion based on environmental exposure.
