SMW Thread Adapter Pin

These pins adapt the standard 1/2-13 threads in our Saunders Machine Works fixture plates to a 1/4-20 thread. The pin locates on the 1/2" precision bore and seals with an o-ring for long-term installation.  Available in Locating (for use like a standard 1/2" dowel pin or SMW Fixturing Pin) and Non-locating (for situations where the pin must sit under the top of the plate). Pins are tightened to the fixture plate using an 8mm or 5/16" hex wrench.
