Method 8 mm or more
Stem
mounting
• Mounting hole tolerance: 8G7(+0.005 to 0.02)
• Clamping screw: M4 to M6
Note • Clamping position: 8 mm or more from the lower edge of the stem • Mounting hole tolerance: 8G7(+0.005 to 0.02)
• Maximum clamping torque: 150 N·cm when clamping with a single M5 screw
• Note that excessive clamping torque may adversely affect plunger movement.

Lug mounting
• Lugs can be changed 90 degrees in orientation according to the application. (The lug is set horizontally when shipped.)
Note • Lugs of some Series 1 models (No. 1911,1913-10 & 1003), however, cannot be altered to horizontal.
• To avoid cosine-effect error, ensure that any type of gauge or indicator is mounted with its plunger in line with the intended measurement direction.

cleaning, contact Mitutoyo for repair.
• Before making a measurement or calibration, confirm if the plunger moves
upward and downward smoothly, and test the repeatability of the zero point.
