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. 224B through J, 238, 239, 436 micrometers and No. 663 micrometer heads, 0.300" diameter anvil and spindle
Product Description
Starrett outside micrometers and micrometer heads having spindle can be instantly converted for measuring wall thickness of tubing, split and full bearings, sleeves and other parts with rounded surfaces of the ball attachment.
