*Note: If the perpendicularity with the stem or parallelism with the reference surface is required
when using Flat Points, it is necessary to use a custom-made indicator/contact-point
assembly. Consult Mitutoyo for advice.

• With all gage heads, the mounting-thread specification for the
interchangeable contact points is M2.5x0.45x5mm, except for the inch
versions of the LGS gages (575-311 and 575-312) which conform to the
UNF thread specification (#4-48 UNF).
•
After replacing a contact point, it should be tightened firmly so that it will
not loosen during usage. (Recommended tightening torque=5N-cm)
•
Ruby and carbide contact points show the best resistance to abrasion.
