Starrett 50644 Radius Gage 15/32 Inch Stainless Steel

Product Description

The STARRETT 50644 is a single-leaf radius gage designed to measure and verify both convex and concave radii at a fixed 15/32 inch (0.47 inch) radius. Finished in satin chrome over a stainless steel body, the leaf provides corrosion resistance and easy readability on the shop floor or in the field. Machinists, tool and die makers, and precision fabricators use this gage to confirm radius dimensions on machined parts, weld preps, sheet metal bends, and formed stock. The single-leaf format keeps the tool compact and straightforward for dedicated go/no-go radius verification at a specific size.

This gage is suited for inspection and layout work in machine shops, fabrication facilities, and maintenance environments where consistent radius checking is required. It handles both convex profiles, such as rounded external edges, and concave profiles, such as fillets and internal curves, with the same leaf. The satin chrome finish reduces glare and surface reflection during use, which improves contrast when fitting the gage against a workpiece to check for gap or contact.

Key Features

• Single leaf measures both convex and concave radii at 15/32 inch
• Stainless steel construction for corrosion resistance and durability
• Satin chrome finish reduces glare and improves readability at the contact point
• Compact single-leaf format for dedicated fixed-radius inspection
• Lightweight at 0.05 pounds for easy handling during inspection tasks

Compatibility

Designed as a fixed-radius inspection leaf gage for use wherever convex and concave radius verification at 15/32 inch is required in machining, fabrication, or maintenance applications.

Installation Notes

No installation is required for this hand-held inspection gage. Store the leaf in a clean, dry location to protect the satin chrome finish and prevent surface corrosion. When checking a workpiece radius, hold the leaf flush against the profile under consistent, light hand pressure and inspect for light gaps to assess fit. Avoid using the leaf as a prying or scraping tool, as this can damage the precision-ground profile edge.
