At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 85. DIN 85 covers slotted pan head machine screws in metric thread sizes M1.6 to M10 (product grade A). The pan head has a flat top with a rounded periphery and a straight slot drive. Superseded in current use by DIN EN ISO 1580, with which it is dimensionally close. Values below are nominal head and slot dimensions.
