Starrett 50635 Radius Gage 15/64 Inch Convex Concave

Product Description

The STARRETT 50635 is a single-leaf radius gage designed to measure and verify both convex and concave radii of 15/64 inch (approximately 0.234 inches). Manufactured from stainless steel with a satin chrome finish, this leaf-style gage provides a durable, corrosion-resistant tool for checking radii on machined parts, weld preps, fillets, and formed edges. Each leaf carries both a convex and concave profile, allowing the technician to check inside and outside radii with the same tool. At 0.05 pounds, the gage is lightweight and easy to handle in tight inspection areas.

This radius gage is suited for use in fabrication shops, machine shops, and field inspection work where confirming a specific radius is required before or after machining, forming, or welding. It is commonly used by machinists, quality control inspectors, pipefitters, and tool and die technicians. The single-leaf format makes it a convenient addition to a radius gage set or a standalone check tool for a specific radius specification called out on a drawing or work order.

Key Features

• Measures 15/64 inch radius — convex and concave profiles on a single leaf
• Stainless steel construction resists corrosion in shop and field environments
• Satin chrome finish reduces glare and surface reflection during inspection
• Lightweight at 0.05 pounds — easy to carry and use in confined spaces
• Maximum radius of 0.23 inches as specified by the manufacturer

Compatibility

Designed as an OEM-style inspection leaf gage for use wherever a 15/64 inch radius specification must be verified on machined, formed, or welded components.

Installation Notes

No installation is required for this inspection gage. Store the leaf flat and away from abrasive surfaces to preserve the profile edges. When checking a radius, hold the gage perpendicular to the workpiece surface and verify full contact along the profile arc. Keep the gage clean and free of burrs to maintain measurement accuracy.
