Starrett PT09157 Round Micrometer Anvil

Product Description

The STARRETT PT09157 is a round replacement anvil designed for use with Mul-T-Anvil micrometers. The anvil is the stationary measuring face of a micrometer, working in tandem with the spindle to establish accurate measurements across a workpiece. This accessory is intended for metrology and precision measurement applications where the original anvil has worn or been damaged and requires replacement. Weighing 0.6 pounds, it is a direct-fit component for the appropriate Mul-T-Anvil micrometer models and is sold individually.

This anvil is suited for use in machine shops, toolrooms, and quality-control environments where Mul-T-Anvil micrometers are part of the standard measurement toolkit. Its round anvil geometry makes it appropriate for outside-diameter and flat-surface measurements. Technicians and machinists performing routine maintenance or reconditioning of micrometer sets will find this a straightforward replacement component.

Key Features

• Round anvil type for flat and outside-diameter measurement applications
• Designed specifically for Mul-T-Anvil micrometer configurations
• Sold as a single unit, allowing targeted replacement without full instrument purchase
• Manufacturer part number 71158 referenced for cross-identification

Compatibility

Designed for use with Mul-T-Anvil Micrometers. Cross-reference manufacturer part number 71158 when verifying fitment.

Installation Notes

Installation of a replacement micrometer anvil should be performed by a qualified machinist or metrologist familiar with precision instrument maintenance. Ensure the micrometer is fully disassembled according to the instrument manufacturer's service procedure before removing or seating the anvil. Avoid applying excessive force during installation, as anvil seating surfaces are precision-ground and can be damaged by improper handling. After installation, verify calibration using a certified gauge block before returning the instrument to service.
