Spi MS110310007 Gage Block Reference Jaws Pair

Product Description

The SPI MS110310007 is a set of reference jaws designed for use with rectangular gage blocks in precision measurement applications. Each pair provides a stable, accurate clamping interface that allows technicians to extend the measuring range of their gage block assemblies. The jaw thickness measures 0.394 inches, and the overall length is 1.97 inches. Accuracy of the reference line to the measuring surface is plus or minus 0.0002 inches, making these jaws suitable for high-precision dimensional inspection work. Sold as a pair of two pieces, they are a standard accessory for metrology setups in tool rooms, calibration labs, and quality control environments.

These reference jaws are intended for precision measurement professionals working in tool rooms, metrology labs, and manufacturing inspection departments. They attach to rectangular gage blocks to create an extended measurement surface for inside, outside, or reference measurements that require tight dimensional tolerances. Typical users include quality control inspectors, calibration technicians, and machinists who require traceable, repeatable measurements in production or standards-compliance environments.

Key Features

• Overall length of 1.97 inches for extended reach in gage block assemblies
• Jaw thickness of 0.394 inches provides a consistent reference surface
• Accuracy of plus or minus 0.0002 inches from reference line to measuring surface
• Compatible with rectangular gage blocks for versatile metrology setups
• Sold as a pair of two pieces for complete jaw set replacement or new assembly

Compatibility

Designed for use with rectangular gage blocks as stated by the manufacturer. Verify block series and jaw interface dimensions against your existing gage block set before installation.

Installation Notes

Installation of reference jaws should be performed by a qualified metrology or calibration technician familiar with gage block wringing and accessory attachment procedures. Clean all mating surfaces thoroughly before assembly to prevent contamination that could affect accuracy. Handle measuring surfaces with care to avoid burrs or corrosion that would compromise the plus or minus 0.0002 inch accuracy specification. Follow your facility calibration procedures and relevant metrology standards when integrating these jaws into a traceable measurement system.
