The VALUE COLLECTION 615-4818 is a fixed-leaf radius gage used to verify and measure curved surfaces with a 9/32 inch radius. The gage is chrome coated over a steel body, which protects the blade from corrosion and wear during regular shop or field use. Technicians use fixed radius gages to check fillet welds, machined profiles, and pipe fittings for conformance to a specified radius. The chrome finish also makes it easier to read the engraved radius marking against the workpiece. At 0.003 pounds, the leaf is lightweight and easy to handle during detailed inspection work.
This gage is appropriate for light industrial, mechanical, and trades applications where quick, no-calculation radius verification is needed. Common uses include inspecting curved fittings, checking bends on sheet metal, verifying radius cuts on machined components, and confirming weld geometry before sign-off. Trade professionals such as pipefitters, fabricators, HVAC techs, and maintenance machinists keep sets of fixed radius gages on hand for rapid go/no-go checks during installation and inspection tasks.
Designed as a standard fixed-leaf radius gage suitable for general inspection and measurement of curved surfaces requiring a 9/32 inch radius across mechanical, fabrication, and trades applications.
No installation is required for this hand inspection tool. Clean the workpiece surface before use to ensure accurate contact between the gage leaf and the measured curve. Store the gage flat and away from abrasive materials to preserve the chrome coating and blade profile. Inspection work involving critical dimensions should follow applicable shop or job-site quality control procedures.
