Cleanroom

These screws are ultrasonically cleaned or IPA cleaned in a cleanroom environment and then packaged.

They are ideal for parts used in FPD manufacturing equipment, semiconductor manufacturing equipment, medical devices,
and food machinery, as well as parts used in cleanrooms.
Can be used immediately upon arrival, saving you cleaning process time.
