Spi 13-315-7 Pin Gage Handle M4 Aluminum 0.626-0.75 in

Product Description

The SPI 13-315-7 is an aluminum pin gage handle designed to accept pin gages with ring diameters ranging from 0.626 to 0.75 inches. It uses an M4 handle size and provides a secure, repeatable grip for precision measurement work. The handle is machined from aluminum to keep weight low while maintaining rigidity during use. At 6.02 inches in length, it gives technicians and quality control personnel a comfortable reach for inspecting bores, holes, and toleranced features. This type of handle is a standard tool in dimensional inspection, used in manufacturing, machining shops, and quality labs wherever pin gage sets are part of the measurement process.

The 13-315-7 is suited for bench inspection and in-process gauging tasks where pin gages in the 0.626 to 0.75 inch diameter range are routinely used. It fits into general metrology workflows in production environments, tool rooms, and quality assurance departments. The M4 handle size is a recognized standard designation for this diameter range, ensuring compatibility with pin gages sized accordingly.

Installation Notes

Pin gage handles are installed by hand — no power tools or torque values apply. Ensure the pin gage shank is fully seated and secure in the handle collet before use. Keep handle and gage surfaces clean and free of burrs or debris that could affect measurement accuracy. Inspection personnel should follow applicable shop metrology procedures and calibration schedules.
