Starrett 50642 Radius Gage 13/32 Inch Convex Concave

Product Description

The STARRETT 50642 is a single-leaf radius gage designed to measure and verify both convex and concave radii of 13/32 inch (0.41 inches maximum radius). Manufactured from stainless steel with a satin chrome finish, this gage provides a durable, corrosion-resistant measuring tool suited for precision work in fabrication, machining, and metalworking environments. Machinists, toolmakers, and quality control technicians use it to quickly confirm radius dimensions on workpieces, fillets, and contoured surfaces without requiring additional measurement equipment.

This gage is appropriate for shop-floor and bench use wherever radius verification is part of the inspection or fabrication workflow. Its compact, single-leaf format makes it easy to carry in a toolbox or apron pocket for quick field checks. The satin chrome finish reduces glare under shop lighting, making it easier to read the fit against a workpiece. It is well suited for light manufacturing, HVAC component fabrication, plumbing fitting verification, and general metalworking inspection tasks.

Key Features

• Measures both convex and concave radii with a single leaf
• Radius size: 13/32 inch (0.41 inches)
• Stainless steel construction for corrosion resistance and long service life
• Satin chrome finish minimizes glare during use
• Compact single-leaf design for easy portability

Compatibility

Designed as a standard single-leaf radius gage for use in general machining, fabrication, and inspection applications requiring verification of a 13/32 inch convex or concave radius.

Installation Notes

No installation is required for this hand-measurement tool. Place the gage leaf against the radius being checked and observe the fit under adequate lighting. Clean the gage and workpiece contact surfaces before use to ensure accurate readings. Store in a dry location away from abrasive materials to preserve the finish and edge profile.
