Starrett 50628 Radius Gage 1/8 Inch Stainless Steel

Product Description

The STARRETT 50628 is a single-leaf radius gage designed to measure both convex and concave radii at 1/8 inch (0.125 inches maximum radius). Machined from stainless steel with a satin chrome finish, it provides corrosion resistance and legible markings in shop environments. The leaf profile conforms to the radius being checked, allowing machinists, fabricators, and tool-and-die technicians to quickly verify inside and outside curves on workpieces. Its compact, lightweight construction at 0.05 pounds makes it easy to carry in a toolbox or apron pocket during inspection tasks.

This gage is suited for use in machine shops, fabrication facilities, and maintenance environments where radius verification is required on machined parts, castings, weldments, or formed components. It is used during in-process inspection and final quality checks on workpieces requiring a 1/8 inch radius profile. The single-leaf format is a direct-comparison tool — no calculation required — making it fast to deploy during production runs or service work.

Key Features

• Measures both convex and concave radii with a single leaf
• Radius size: 1/8 inch (0.125 inches)
• Stainless steel construction resists corrosion in shop environments
• Satin chrome finish reduces glare and improves readability
• Lightweight at 0.05 pounds for easy handling and portability

Compatibility

Designed as a direct-comparison radius gage leaf for general inspection use on machined, formed, or cast components requiring a 1/8 inch radius verification.

Installation Notes

No installation is required. This is a hand-held inspection tool used by placing the gage leaf against the workpiece radius and checking for gap or fit. Clean the gage and workpiece contact surfaces before use to ensure accurate comparison. Store in a protective case or pouch to prevent damage to the leaf profile.
