Abstract
Overview
ISO 272:1982 is an international standard developed by the International Organization for Standardization (ISO) that specifies the widths across flats for hexagon fastener products. This includes hexagon bolts, screws with hexagonal heads, hex nuts, and hex flange nuts. The standard ensures a logical ratio between the underhead (or nut) bearing surface area and the tensile stress area of the screw thread, which is essential for maintaining appropriate compression rates and securing mechanical joints efficiently.
