• 0.38" (9.5 mm) diameter stem with 4 to 48 UNF thread

Mitutoyo 2923AB-10 Standard Type Series 2 Dial Indicator has an outer frame with an outside diameter of 57mm. All types come with limit pins and an outer frame clamp as standard. Secured adhesion between the outer frame and crystal as well as the use of an O-ring ensure countermeasures against water and oil permeation via the front face. The stem spindle is made of high-strength quench-hardened stainless steel which resists strenuous use and a carbide contact point is used. The grand gear uses stainless steel that is resistant to wear and deformation an application of hard coating on the surface of the crystal makes the gauge highly scratch as well as chemical resistant. This model has Jeweled Bearings and a Flat Back with a range of .05" and .01" per revolution, .0001" graduation and 0-5-0 Dial Reading with a 3/8" Stem., The Mitutoyo “A" Series Dial Indicators have scratch resistant, anti-glare coated crystals just like our popular Test Indicators. They also have a standardized stop screw thread to M2.5x0.45, increased mounting stem length*, a redesigned spindle for waterproof models allowing for additional contact points to be used, a tapered hand/pointer base which makes repairs easier when needed, tolerance clips are now optional, a change in stop screw shape*, and the bezel and dust cap colors are black.
