Dowel pins are ground cylindrical pins primarily manufactured for precise locating devices in machinery and assemblies.
Dowel pins are ground cylindrical pins primarily manufactured for precise locating devices in machinery and assemblies. Steel dowel pins are machined to tight tolerances with the DIN and ISO standard pins being m6 on the diameter. The corresponding holes are usually reamed to allow for a press fit, clearance fit or transition fit.
When designing engineered components, dowel holes are often used as reference points to control positioning alignment to attain repeatable assembly quality. When dowel pins are pressed into blind holes it is recommended that dowels with ‘air release flats’ are used to allow displacement of air preventing damage to the work piece or the ejection of the dowel.
Steel dowel pin standards include:
Metric Pins
BS 8734 / ISO 8734 A / ISO 8734 B limits
BS 8735 / ISO 8735 A / ISO 8735 B limits
ISO 2338A / ISO 2338A (stainless)
DIN 6325
DIN 7979
DIN 7
ANSI ASME B
Imperial Pins
BS 1804 limits
ANSI ASME B
