M4 Screws
M4 Screws Selection
M4 machine screws are precision fasteners used for light mechanical assembly, electrical fittings, and general construction where a smaller diameter fixing is required. M4 refers to the 4mm shank diameter with a 0.70mm metric coarse thread, ensuring compatibility with standard nuts, washers, and threaded holes.
Available in both Countersunk and Pan Head styles, M4 machine screws provide reliable performance across a wide range of applications. Finishes include Bright Zinc Plate for general use, and Stainless Steel 304 and 316 for enhanced corrosion resistance in demanding or outdoor environments.
