The fillet weld gauge allows fast, accurate measurement of eleven (11) fillet weld sizes: 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 5/8", 3/4", 7/8", and 1" as well as their metric equivalents. This tool easily aids in determining weld sizes, either concave or convex.

Each gauge blade is made of 1-1/4" x 4" stainless steel to resist rust and bending. Blades are deburred to remove rough edges. All sizes and numerals are engraved into the surface for easier reading.
