Spi 14-180-4 Taper Gage 1 Leaf 1/32 to 5/8 Inch Range

Product Description

The SPI 14-180-4 is a single-leaf taper gage used to measure gap widths, slot widths, and flange face-to-face clearances in fabrication, maintenance, and mechanical assembly work. The leaf spans a measurement range of 1/32 inch to 5/8 inch with a 1/64 inch graduation, giving technicians precise incremental readings without the need for calipers or feeler gage sets. At 6 inches in length, the blade reaches into confined spaces while maintaining a stable grip. This tool is used by machinists, millwrights, pipefitters, and maintenance technicians wherever a direct-read gap measurement is needed in the field or on the shop floor.

The 14-180-4 is suited for applications that require quick, repeatable gap checks in tight clearances. Common uses include measuring flange face-to-face dimensions and checking hole or slot widths during fit-up and inspection. The single-leaf design keeps the tool compact and eliminates the need to fan through multiple blades when a fixed measurement range is acceptable. It is a practical addition to any field service kit or toolbox where fast dimensional verification is part of daily workflow.

Key Features

• Measurement range of 1/32 inch to 5/8 inch covers common gap and clearance checks
• 1/64 inch graduation for precise incremental readings
• 6-inch blade length reaches into recessed or confined measurement points
• Single-leaf construction keeps the tool compact and easy to handle
• Suited for flange face-to-face dimensions, slot widths, and hole clearances

Compatibility

Designed as a general-purpose taper gage for mechanical assembly, fabrication inspection, and maintenance applications where gap measurements in the 1/32 inch to 5/8 inch range are required.

Installation Notes

Insert the tapered blade into the gap or slot until contact is felt on both faces, then read the graduation at the point of entry. Ensure mating surfaces are clean and free of burrs before measuring to avoid inaccurate readings. No special tools or fasteners are required for use. Store the gage away from moisture and corrosive materials to maintain blade integrity and legibility of the graduation markings.
