DIN7h8 Unhardened Dowel Pins
DIN7h8 Metric Unhardened Dowels are produced with an 'h8' push fit tolerance in both Mild Steel and Stainless Steel. Our standard metric diameter range is from 0.8mm up to 20mm diameter and lengths 3mm to 120mm are available. This range of unhardened pins is produced from material 1.0718 Mild Steel or 1.4305 (A2) Stainless Steel.
Please note that the nominal length of a DIN7h8 pin is measured along the parallel surface only, the chamfers at each end of the pin are not calculated as part of the nominal length.
