Description

The MITUTOYO 126-806 is a replacement anvil accessory designed for use with screw thread micrometers. Machined from high grade steel, this 60-degree anvil mates with the measuring spindle to contact thread flanks at the correct angle for accurate pitch diameter measurement. It is a component-level replacement intended for metrology professionals, tool room technicians, and quality control personnel who service or maintain precision measuring equipment. The 60-degree included angle is the standard form for unified and metric V-thread measurement.

This anvil is used in thread measurement applications where the existing anvil on a 326 or 126 Series screw thread micrometer has worn or been damaged. Screw thread micrometers equipped with interchangeable anvil sets are commonly found in machine shops, manufacturing facilities, and inspection departments. The 126-806 covers a pitch range of 4.50 to 3.50, making it suitable for coarser thread pitches within that range. Installation is performed during routine instrument maintenance or when changing pitch ranges on compatible micrometer bodies.

Installation Notes

Anvil replacement on precision micrometers should be performed by a qualified metrologist or instrument technician familiar with the micrometer model. The instrument should be removed from service and cleaned before replacing contact elements. After installation, the micrometer should be re-zeroed and verified against a calibrated thread wire or standard before returning to use. Refer to the instrument manufacturer’s service documentation for anvil seating and locking procedures specific to the micrometer body.
