Spi 10-756-5 Micrometer Setting Ring 7 in Id

Product Description

The SPI 10-756-5 is a precision micrometer setting ring designed to calibrate and verify inside micrometers before and during use. With a 7-inch inside diameter, this setting ring provides a traceable reference point that allows technicians and machinists to zero or confirm the accuracy of their bore measuring instruments. Setting rings are a standard accessory in precision measurement work, used wherever consistent, repeatable inside diameter readings are required. The 10-756-5 is specifically designed for use with SPI Hole-Mike Series micrometers.

This setting ring is suited for precision measurement applications in machine shops, manufacturing facilities, and quality control environments. It is used when setting up or verifying inside micrometers measuring bores at 7 inches. Typical users include machinists, metrologists, and quality assurance technicians working with tight-tolerance components. The ring supports accurate measurement workflows where instrument verification before use is required by shop procedure or quality standard.

Key Features

• 7-inch inside diameter provides a precise reference for micrometer calibration and verification
• Designed specifically for use with SPI Hole-Mike Series inside micrometers
• Supports repeatable, accurate bore measurement by providing a known reference diameter
• Packaged as a single unit for individual instrument setup

Compatibility

Designed for use with SPI Hole-Mike Series inside micrometers. Verify that your micrometer range covers the 7-inch nominal size before use.

Installation Notes

Setting rings do not require installation in the traditional sense but should be handled with care to avoid nicks, scratches, or drops that could affect the reference surface. Store the ring in its case when not in use. Clean the ring and micrometer anvils with a lint-free cloth before each use. Setting rings should be conditioned to room temperature before taking reference measurements to avoid thermal expansion errors.
