Critical points to check
Surface finish
The surface can be
checked with surface gauge or visually for finish. Poor thread
finish can lead to seizing up of threads.
Checking reamed holes
Reamed holes can be
checked using measuring instruments such as vernier callipers,
telescopic gauges or inside micrometers. For quick checking,
go/no-go plug gauges can be used
