Starrett 50636 Radius Gage 1/4 Inch Stainless Steel

Product Description

The STARRETT 50636 is a single-leaf radius gage designed for measuring both convex and concave radii of 1/4 inch (0.25 inches). Constructed from stainless steel with a satin chrome finish, this gage is built for repeated use in shop, field, and fabrication environments. Machinists, pipefitters, and fabricators use leaf-style radius gages to verify fillet radii, rounded corners, and curved profiles on workpieces, weld beads, and machined parts. The satin chrome finish reduces glare during inspection, making it easier to identify light gaps between the gage leaf and the workpiece surface. Weighing just 0.05 pounds, it is easy to carry and store without adding bulk to a tool kit.

This radius gage leaf is suited for use in precision layout and inspection work across metalworking, welding, plumbing, and general fabrication trades. It is appropriate for both shop-floor quality checks and field verification where a specific 1/4-inch radius must be confirmed on formed, machined, or welded components. Each leaf measures a single radius value, allowing for quick go/no-go profile checks without additional setup. The compact form factor makes it practical for tight-clearance inspections on assembled parts or inside fixtures.

Key Features

• Measures both convex and concave 1/4-inch radii with a single leaf
• Stainless steel construction resists corrosion and wear in shop environments
• Satin chrome finish minimizes glare for accurate light-gap inspection
• Lightweight at 0.05 pounds for easy handling and tool-bag portability
• Single-leaf design allows targeted inspection without sorting through a full set

Compatibility

Designed as an OEM-style inspection tool for verifying 1/4-inch radii on machined, formed, or welded workpieces across general metalworking and fabrication applications.

Installation Notes

No installation is required for this inspection tool. To use, hold the appropriate leaf face against the radius being checked and observe the light gap between the leaf and the workpiece. Power down any rotating equipment and secure workpieces before performing radius checks on machinery. Keep leaves clean and free of burrs to maintain measurement accuracy.
