QA Technology highly recommends that holes initially drilled in fixture plates be verified using pin gauge tools (PG Tools) due to the tolerances of purchased drill bits which can be undersized by as much as .0005” or more. The machine feed rate, RPM and material used, can also affect the hole size. Undersized holes will not pass go-no-go pin gauge testing. Undersized holes may create problems when inserting the sockets. Therefore, QA Technology strongly suggests the use of pin gauges for hole size verification before attempting socket installation during the assembly of the fixture.
