Flat head hex socket cap screws, also known as countersunk socket screws, are designed to provide a smooth, flush surface once installed. Their internal hex drive allows for secure torque application, while the flat, countersunk head fits seamlessly into drilled holes, making them ideal for applications requiring an unobtrusive finish.
We offer a broad range of sizes and specifications, including popular models like M4 x 16mm, M5 x 20mm, M6 x 25mm, M8 x 30mm, and M10 x 40mm, suitable for machinery, electronics, automotive, and precision engineering projects.
