Spi 19-907-5 Class Zz Minus Plug Pin Gage 0.907 in

Product Description

The SPI 19-907-5 is a Class ZZ minus plug pin gage designed to verify hole diameter tolerances in precision machining and inspection applications. Measuring 0.907 inches in diameter, this go/no-go style gage is held to a minus tolerance of 0.0002 inches, making it suitable for dimensional inspection tasks where tight dimensional control is required. Constructed from steel, the 19-907-5 delivers the rigidity and wear resistance expected on a production floor or in a quality control environment. Machinists, quality technicians, and tool-room professionals use plug pin gages like this one to confirm bore sizes quickly and repeatably without complex measurement setups.

This gage is used in manufacturing, tool rooms, and inspection departments where bore diameter verification is part of standard quality control workflow. It is appropriate for checking drilled, reamed, or bored holes in metal and other materials where a 0.907-inch nominal diameter is the target dimension. The minus classification means the gage is manufactured to the lower end of the tolerance band, consistent with Class ZZ plug gage standards for general inspection use.

Key Features

• 0.907-inch nominal diameter for precise hole verification at that size
• Class ZZ minus tolerance classification — 0.0002-inch tolerance for general inspection work
• Steel construction provides durability and dimensional stability under repeated use
• Compact and lightweight at 0.2 pounds — easy to handle during inspection
• Single-piece packaging with a minimum order quantity of one unit

Compatibility

Designed as an OEM-style replacement or direct-use plug pin gage for any inspection or manufacturing application requiring a 0.907-inch diameter Class ZZ minus go/no-go gage.

Installation Notes

Plug pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store the gage in its protective case or on a padded surface away from other tooling to avoid nicks or burrs on the gaging surface. Before use, verify the gage against a calibrated master ring gage or setting standard to confirm it is within calibration. Follow your facility's established gage calibration and handling procedures in accordance with applicable quality management standards.
