Key Features
- Easily applied by snapping on to end of either anvil or spindle, thus permitting two attachments to be used together
- Balls are hardened, measure 0.200" in diameter, and move freely in the retainer, insuring positive contact with anvil and spindle
- The diameters, 0.200" of each ball used must be subtracted from the micrometer reading
- Applied for Nos. 216, 231, 436.1, 733, 734, 1212 and 1230 micrometers, 0.250" diameter anvil and spindle
Product Description
