Machine Screw - Recess Countersunk - M4x30mm

When a strong and resilient fastening is essential, machine screws offer the ideal solution. These fasteners are specifically engineered to clamp metal parts together in machinery, providing strong and durable joints that outperform many other screw types. Unlike standard screws with tapered threads, machine screws feature a uniform thread and a flat tip, which requires a pre-threaded hole to be tapped before insertion. 

Among the various head styles available, the countersunk head is designed to sit flush with the material's surface, ensuring a clean, smooth finish once installed.
