ISO 2338 Dowel Pin

ISO 2338 Dowel Pins, referred to as parallel pins, are headless solid cylindrical pins manufactured to a precise diameter. Used to align parts and function as hinge and wrist pins, roller bearings or as shafts, one end is chamfered (~15°) to facilitate insertion while the opposite end may be radiused or dimpled. For press-fit applications, dowel pins should be pressed into position—do not use impact force because pin splintering may occur. Tolerance Class m6, oversized, and undersized h8 are available in plain finish unhardened steel, which can rust, and stainless steel. The "limit deviations" (or "tolerance zone") varies by diameter; for example, the tolerance of an M4 m6 pin is +0.004 to +0.012 mm while an M4 h8 pin is 0 to -0.018 mm. Length is measured from end to end including the chamfer like inch series dowel pins but unlike DIN 7. ISO 2338 Dowel Pins may be similar to DIN 7.
