Metric DIN 933 Hexagon Head Cap Screws / Bolts are externally threaded fasteners with a hexagonal washer faced head and a chamfered tip to facilitate mating with an internally threaded component. DIN 933 hex screws have a fully threaded shank and are manufactured to very strict tolerances. The Straight Wire offers one of the most complete ranges of metric screws, bolts and other inch and metric industrial fasteners for immediate delivery from stock.
DIN 933 has been withdrawn and replaced by ISO 4017. There is some similarity (nominal dimensions extended | Width across flats changed for M10, M12, M14 and M22).
