M4 Countersunk Self-Tapping Screw Phillips

Get a secure, flush-finish fastening solution with these M4 Countersunk Self-Tapping Screws, featuring a Phillips (cross) drive for reliable torque transfer without slippage. The countersunk flat head sits perfectly level with the surface once installed, making it ideal for applications where a clean, snag-free finish matters, such as electronics enclosures, panel mounting, and general hardware assembly.

Made from stainless steel, these screws resist corrosion and rust, holding up well in both indoor and outdoor conditions over the long term. The self-tapping thread design cuts its own mating threads directly into pre-drilled pilot holes in wood, plastic, and thin sheet metal, eliminating the need for separate nuts or threaded inserts in many applications. This makes installation faster and more efficient, particularly useful for hobbyists working on enclosures, 3D-printed housings, or DIY electronics projects that need a strong, reusable fastening point.

Available in multiple lengths to suit different material thicknesses and project requirements, these screws are a practical addition to any hardware bin. They’re commonly used by makers and technicians for securing PCBs, mounting brackets, closing project boxes, and general repair work where a low-profile, corrosion-resistant fastener is needed.
