Custom 52100 Dowel Pins - 7MM X 32MM

These custom 52100 dowel pins were fairly ordinary in dimensional requirements but the material was quite tricky and time intensive to procure.  C-52100 DFARS material per S5452100-22810A specification was used with 91.5 ksi tensile strength.  Heat treatment was performed to achieve hardness of 81-83.5 HRA per customer requirements.  Material certs and a certificate of conformance was provided with the parts and all production processes were done domestically in the USA.
