The VALUE COLLECTION 615-4812 is a 3/16-inch radius gage used to verify and measure curved profiles, fillets, and radii on machined or fabricated parts. The gage is constructed from steel with a chrome coating, which resists corrosion and provides a smooth reference surface for accurate comparisons. At 0.003 pounds, it is a compact, lightweight hand tool suited for bench use or field inspection. Machinists, tool and die workers, and maintenance technicians use this type of gage to confirm that a radius matches a specified dimension before or after machining operations.
This radius gage is appropriate for general inspection tasks in manufacturing, fabrication, and maintenance environments. It is used to check inside and outside radii on weld joints, castings, molded parts, and machined components. The 3/16-inch size targets a specific radius profile and is typically used as part of a matched set covering a range of radius sizes, though it functions as a standalone inspection tool for that single dimension.
Designed as a general-purpose radius gage for use in machining, fabrication, and maintenance inspection applications where a 3/16-inch radius must be verified.
No installation is required for this hand inspection tool. Hold the gage against the radius to be measured and compare the contact fit visually under adequate lighting. Ensure the part surface is clean and free of burrs or debris before measuring to avoid false readings. Store the gage in a dry location to preserve the chrome coating and prevent corrosion.
