Starrett 50627 Radius Gage 7/64 Inch Stainless Steel

Product Description

The STARRETT 50627 is a single-leaf radius gage designed to check both convex and concave radii at a 7/64 inch (0.109 inches) measurement. Constructed from stainless steel with a satin chrome finish, this gage provides a corrosion-resistant, easy-to-read surface suited for shop floor use. Each leaf covers both the convex and concave profile of the specified radius, allowing a technician to verify inside and outside contours with a single tool. It is used by machinists, pipefitters, and precision tradespeople to confirm radius dimensions during fabrication, inspection, or layout work.

This radius gage is suited for use in light manufacturing, HVAC fabrication shops, plumbing rough-in work, and general metalworking environments where confirming curved profiles is part of quality control. The compact size and low weight make it easy to carry in a toolbox or apron pocket for on-site verification tasks. It functions as a go/no-go reference for machined, formed, or welded radius surfaces during production or installation inspection.

Key Features

• Measures 7/64 inch radius — covers both convex and concave profiles on a single leaf
• Stainless steel construction resists corrosion and wear in shop environments
• Satin chrome finish reduces glare and improves readability under shop lighting
• Lightweight at 0.05 pounds — easy to carry and handle during inspection tasks
• Single-piece leaf design simplifies use with no moving parts to maintain

Compatibility

Designed as a standard radius gage leaf for verifying 7/64 inch convex and concave radii on machined, formed, or fabricated components across general metalworking and trade applications.

Installation Notes

Radius gages are hand-held inspection tools and require no installation. Store the leaf in a clean, dry location to protect the contact edges from nicks or burrs that could affect accuracy. Before use, inspect the gage edge for damage that could produce a false reading. No calibration tools or power shutoff procedures are required for use.
