Bolts BS4183 Countersunk Slotted Flat - M14 View 04
BS4183 Countersunk Slotted Flat screws (technically classified as machine screws under the British Standard) are high-precision metric fasteners designed to sit completely level with or just below the surface of the material. Manufactured to strict BS 4183 standards, they feature a cone-shaped head with a flat top that nests perfectly into a pre-drilled, countersunk hole. The "slotted" design means the head has a single straight groove made for standard flat-blade screwdrivers, offering a classic, clean appearance. Because they create a smooth, snag-free surface and require only basic tools to install, these screws are widely used in electrical panels, classic machinery components, and precision engineering where a flush finish is essential.
