The SPI MS170310009 is a five-piece spare part kit designed to support the maintenance and repair of outside micrometers. The kit consolidates the most commonly replaced consumable and adjustable components into a single package, reducing downtime when a micrometer needs a quick service. Components included are a battery case, locking screw, ratchet stop, and wrench. The package weighs 0.19 pounds and is compact enough to store in a toolbox or service kit alongside the instrument it supports. This kit is appropriate for calibration technicians, metrology shop personnel, and precision measurement professionals who maintain outside micrometers in the field or in a lab setting.
The MS170310009 kit is intended for use with outside micrometers and serves as a targeted replacement-parts solution for routine servicing. It is well suited to production floors, quality control labs, and tool cribs where outside micrometers see regular use and periodic component wear. Having these spare parts on hand eliminates the need to source individual hardware components separately when a ratchet stop wears or a locking screw is misplaced during calibration work.
Designed for use with outside micrometers. Verify fitment against the specific SPI outside micrometer model being serviced before installation.
Service and parts replacement on precision measuring instruments should be performed by a qualified calibration technician or metrology professional. Before disassembling any micrometer, ensure the instrument is clean and free of chips or debris. Use only the appropriate wrench supplied in the kit to avoid damaging precision threads or seating surfaces. After reassembly, verify instrument calibration against a certified gauge standard before returning the micrometer to service.
