Built from hardened tool steel, this gage features a white dial face for clear, direct readings in the field or at the bench. It covers a measurement range of 0.16 to 0.36 inches, making it well-suited for inspecting fastener seating in metal fabrication, machining, and sheet metal work. Machinists, tool and die makers, and quality control technicians rely on countersink gages to verify that countersinks meet specification before final assembly.\u003c\/p\u003e\u003cp\u003eThis gage is used wherever 90-degree countersinks must be checked for correct diameter and depth consistency. Typical applications include production inspection of drilled and countersunk holes in structural components, aerospace sheet metal, and general machined parts. The compact size and direct-reading dial make it practical for both shop floor use and inspection bench setups. It is appropriate for any trade or manufacturing environment where fastener flush-mount accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0.16 to 0.36 inches covers common small-fastener countersink sizes\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for 90-degree countersink angle verification\u003c\/li\u003e\n\u003cli\u003eHardened tool steel construction for durability in production environments\u003c\/li\u003e\n\u003cli\u003eWhite dial face provides high-contrast, easy-to-read measurements\u003c\/li\u003e\n\u003cli\u003eCompact design suited for bench inspection and in-process shop floor checks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 90-degree countersunk holes within the 0.16 to 0.36 inch diameter range, as found in standard countersunk fastener applications across metal fabrication and machining.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis is a precision measuring instrument, not an installed component. Handle with care to avoid dropping or contacting abrasive surfaces that could affect calibration. Store in a protective case when not in use.
