The SPI 13-310-8 is an aluminum pin gage handle set designed for use with ring and plug thread gages in precision measurement applications. The set includes eight pin gage handles sized to accommodate a wide diameter range, from 0.0110 inches up to 1.0000 inches. Constructed from aluminum, the handles provide a lightweight yet rigid grip for accurate hand-gaging work. This set carries a handle size designation of M0 and is intended for use by machinists, quality control technicians, and tool-room professionals who require reliable, repeatable gage handling during inspection routines.
This handle set is suited for production floor and quality lab environments where ring gages and plug gages are used to verify bore diameters, thread forms, and hole tolerances. The broad diameter range covered by the eight included handles makes the set practical for shops that work across multiple part families and gage sizes. It is commonly used in manufacturing, aerospace, and automotive precision inspection workflows where consistent handling technique directly affects measurement accuracy.
Designed as an OEM-style replacement and standard fitment for use with ring gages and plug thread gages requiring M0 size handles within the 0.0110 to 1.0000 inch diameter range.
Installation and use of gage handles should be performed by qualified metrology or tool-room personnel familiar with precision hand-gaging procedures. Ensure gage pins are fully seated and secured in the handle before use to prevent measurement error or dropped tooling. Do not overtighten collet mechanisms, as this can distort gage pin geometry. Store handles in a clean, dry environment away from abrasive materials to preserve surface finish and measurement integrity.
