M3 Screws
M3 Screws selection
Our M3 machine screws are compact, precision fasteners ideal for electronics, small machinery, and light assembly work. M3 refers to the 3mm shank diameter with a 0.50mm metric coarse thread, designed to fit standard nuts, washers, and pre-tapped holes for accurate fastening. Although technically a bolt when used with a nut or threaded component, machine screws are generally called screws due to their distinctive screw head.
Available in Countersunk and Pan Head styles, these screws provide secure fixing with a clean finish. Finishes include Bright Zinc Plate for general indoor use, or Stainless Steel 304 and 316 for long-term corrosion resistance in demanding or outdoor environments.
All M3 machine screws are available in a range of lengths and are stocked for immediate despatch Australia-wide. M3 Screws are sold in trade boxes and bulk cartons for volume users. All orders from Scrooz Fasteners over $99 ship free Australia wide.
