Spi CMS160726120 Screw Micrometer Anvil 8-5 Tpi

Product Description

The SPI CMS160726120 is a screw micrometer anvil designed for use with SPI thread micrometers. It features a 60-degree anvil profile engineered to seat accurately in thread grooves for reliable pitch measurement. The anvil covers a pitch range of 8 to 5 TPI, supporting measurements from 3.5 mm to 5.0 mm. Constructed from bright-finish steel, it provides the dimensional stability and surface hardness required for repeatable metrology work. This anvil is a replacement or supplemental accessory component installed by machinists, toolroom technicians, and quality-control professionals who use thread micrometers in production or inspection settings.

This anvil is suited for thread measurement applications in machining, manufacturing, and inspection environments. It is used wherever SPI thread micrometers are deployed to verify thread pitch on fasteners, threaded bores, or machined components. The pitch range of 8 to 5 TPI makes it applicable to coarser-thread work within that measurement window. It is sold as a single-piece accessory and is a direct fit for the SPI thread micrometer product line.

Key Features

• 60-degree anvil angle for accurate seating in standard thread forms
• Pitch range: 8 to 5 TPI
• Measurement range: 3.5 mm to 5.0 mm
• Bright-finish steel construction for dimensional stability
• Single-piece accessory sold individually

Compatibility

Designed for use with SPI thread micrometers as stated by the manufacturer. Confirm anvil pitch range matches the thread specification being measured before installation.

Installation Notes

Thread micrometer anvils are installed by machinists or metrology technicians following the micrometer manufacturer's accessory-swap procedure. Ensure the micrometer is zeroed and calibrated after replacing or swapping anvils. Handle the anvil contact surfaces with care to avoid nicks or contamination that could affect measurement accuracy. Store in a protective case when not in use to maintain surface finish integrity.
