Bolts BS4183 Countersunk Cross Recessed Flat - M5 View 02
BS4183 Countersunk Cross Recessed Flat screws (technically classified as machine screws under the British Standard) are high-precision metric fasteners engineered to sit perfectly level with or just below the surface of the material they secure. Manufactured to strict BS 4183 dimensional standards, these fasteners feature a distinct 90-degree cone-shaped head that tapers into a flat top, allowing them to embed seamlessly into pre-drilled, countersunk holes. The "cross recessed" design denotes a standard Phillips or Pozidriv head drive type, which provides excellent torque control and slip resistance for standard screwdrivers and assembly tools during fast-paced installation. Because they create a smooth, obstruction-free finish that eliminates snagging risks, they are a fundamental choice across consumer electronics, industrial machinery panels, furniture assembly, and precision mechanical engineering.
