What is BS 1769 - Unified black hexagon bolts, screws, and nuts about?
Bolts, screws and nuts are designed to work so that they strengthen whatever they are holding together. BS 1769 focuses on Heavy Series bolts, screws and nuts having hexagon sizes which are larger in proportion to the nominal diameter of thread than those in the Normal Series. The tolerances are comparatively wide, as is usual in the case of black bolts and nuts, but it is recognized that bolts and nuts of these dimensions may be required with a higher grade of finish for certain applications, and requirements are accordingly included in respect of bolts faced under the head and machined on the shank and machined nuts.
BS 1769 relates to the Heavy Series of Unified black hexagon bolts, screws and nuts having Unified screw threads in a range of nominal sizes from" in. to 2 in. inclusive.
