M4 Screws selection:
Find all our M4 diameter screws in this category. Below you'll find all our listings for machine screws in M4. Although technically a bolt as its often used with a nut or threads into a component machine screws are generally referred to as a screw as they feature a screw head. If it's a wood screw your looking for, please go to our screws section in the menu, we do also stock screws in 8g (M4 equivalent) in a variety of head types. We stock machine screws in zinc plated and stainless steel in both countersunk and panhead options. You'll find these listed below in both packs, trade boxes and cartons for volume users. Machine screws all have a Philips #2 drive.
For specific types of screws, please use the top menu or use the filtering panel to the left hand side of the page
