Starrett 50634 Radius Gage 7/32 Inch Convex Concave

Product Description

The STARRETT 50634 is a single-leaf radius gage designed to measure and verify both convex and concave radii of 7/32 inch (0.21875 inches, maximum 0.22 inches). Constructed from stainless steel with a satin chrome finish, it resists corrosion and provides a clean, glare-reduced surface for accurate visual comparison. Machinists, toolmakers, and precision fabricators use this gage to confirm fillet radii, corner radii, and profile contours on machined or formed parts. At 0.05 pounds, it is compact and easy to handle in production or inspection environments.

This radius gage leaf is suited for use in machine shops, fabrication facilities, and quality control stations. It handles both internal (concave) and external (convex) radius checks in a single leaf, making it efficient for verifying part conformance on turned, milled, or stamped components. The 7/32 inch radius size is common in general machining work where moderate fillet or corner dimensions are specified on engineering drawings.

Key Features

• Measures convex and concave radii of 7/32 inch per single leaf
• Maximum radius 0.22 inches for precise profile verification
• Stainless steel construction resists corrosion and wear
• Satin chrome finish reduces glare during visual comparison
• Lightweight at 0.05 pounds for easy bench or field use

Compatibility

Designed as a standard single-leaf radius gage for general-purpose inspection and layout work where 7/32 inch convex and concave radius verification is required.

Installation Notes

Radius gages require no installation. A licensed or trained machinist or quality inspector holds the gage leaf against the workpiece radius and compares fit visually or with a light gap check. Ensure the part surface is clean and free of burrs before gaging to avoid false readings. Store the leaf in a protective case or pouch when not in use to prevent nicks and wear to the profile edge.
