Starrett 55816 Radius Gage 15mm Stainless Steel

Product Description

The STARRETT 55816 is a 15mm radius gage designed for precise measurement of curved surfaces in fabrication, machining, and metalworking applications. Constructed from stainless steel with a satin chrome finish, this individual leaf gage measures both convex and concave radii, giving technicians and machinists a reliable single-tool solution for radius verification. The leaf-style design allows for quick profile matching against workpiece edges and fillets. This type of gage is a standard instrument for quality control checks on machined parts, weldments, and formed sheet metal components where radius conformance is a critical specification.

The STARRETT 55816 is suited for use in machine shops, fabrication facilities, HVAC sheet metal shops, and industrial maintenance environments. It is appropriate wherever a 15mm radius must be verified on formed, cast, or machined surfaces. The individual leaf format makes it easy to store alongside other radius gages in a standard tool kit or inspection station. Both convex and concave profiles are accommodated by a single leaf, reducing the number of tools needed during inspection rounds.

Key Features

• Measures a maximum radius of 15mm for both convex and concave profiles on a single leaf
• Stainless steel construction resists corrosion and wear in shop environments
• Satin chrome finish reduces glare for improved readability during inspection
• Convex and concave radii gauging combined on each leaf for versatile use
• Compact leaf-style form fits easily into toolboxes and inspection kits

Compatibility

Designed as an individual replacement or supplementary leaf for use in standard radius gage sets, compatible with general inspection workflows requiring 15mm radius measurement on machined or formed parts.

Installation Notes

Radius gages require no installation and are used as hand-held inspection tools. Hold the gage leaf flat against the workpiece radius and check for light gaps to confirm fit. Keep the gage clean and free of burrs or debris that could affect measurement accuracy. Store in a dry location away from corrosive materials to preserve the stainless steel surface and satin chrome finish.
