About M4 Screws

M4 screws should be in every toolbox. They can be used for a variety of applications and the heads vary in shape. Some look like bolts with heads that remain above the surface of the hole, while others have flat heads that are flush with the surface. The flat versions typically stay in place better, but are more difficult to remove. Some of the screws have an Allen head, pozi pan head, or slotted pan head. M4 screws have a flat tip, which means that a hole must be pre-drilled before the screw can be inserted. Consider which tools are needed to install them. Find M4 brass screws or an M4 thumb screw on eBay. Some of Top-rated sellers list them in new and used conditions, and many offer free delivery.
