This part of BS1580 specifies limits of sizes, and tolerances, for single-start, clearance-fit unified screw threads, in inch units with diameters below in. This part of BS1580 specifies unified screw threads from Number 0 (0.060 in diameter) to Number 12 (0.216 in diameter), known as the “numbered sizes” in the following standard series: a coarse thread (UNC) series; a fine thread (UNF) series; for Number 12 threads, an extra fine (UNEF) 32 threads per inch diameter/pitch combination. NOTE Unified screw threads below in diameter for attachment purposes and for general use in the aircraft industry are specified in AnnexA.
