Starrett 50623 Radius Gage 3/64 Inch Leaf

Product Description

The STARRETT 50623 is a single-leaf radius gage designed to measure both convex and concave radii of 3/64 inch (0.047 inches maximum radius). Finished in satin chrome over stainless steel, the leaf resists corrosion and maintains dimensional stability in shop environments. Machinists, tool and die makers, and quality control technicians use this gage to verify fillet and corner radii on machined parts, castings, and fabricated components. The compact single-leaf form stores easily in a toolbox and delivers fast, repeatable go or no-go reference checks without requiring a full radius gage set.

This gage is suited for use in precision machining shops, metal fabrication facilities, and inspection departments where accurate radius verification is part of routine quality control. It measures both convex and concave profiles from a single leaf, making it useful for checking inside corners and outside fillets on the same workpiece. Typical applications include checking turned parts, stamped components, and weld preps where tight radius tolerances must be confirmed before assembly or finishing.

Key Features

• Measures 3/64 inch radius with convex and concave reference profiles on a single leaf
• Stainless steel construction for corrosion resistance and long service life
• Satin chrome finish reduces glare and surface wear
• Single-leaf format for targeted inspection without carrying a full set
• Compact and lightweight at 0.05 pounds for easy portability

Compatibility

Designed as a direct-use radius reference gage for machined, cast, and fabricated parts requiring verification of 3/64 inch convex or concave radii. Compatible with general metrology workflows wherever radius leaf gages are specified.

Installation Notes

No installation is required for radius gages. Clean the gage leaf and the workpiece contact surface before use to remove chips, oil, or debris that could affect the fit reading. Hold the leaf firmly against the radius being checked and verify fit by observing light gap at the edges. Handle with care to avoid bending the leaf, as deformation will compromise measurement accuracy.
