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.
