It covers a measurement range of 0 to 1 inch with a resolution of 0.00005 inches (0.001 mm) and an accuracy of 0.00015 inches. The ball anvil contacts the workpiece at a single point, allowing repeatable readings on surfaces that would otherwise produce inaccurate contact with a standard flat anvil. Mechanical operation with a ratchet stop thimble ensures consistent measuring force on every use. A satin chrome finish reduces glare and resists corrosion in shop environments. Machinist professionals and quality control technicians rely on this tool for precision dimensional inspection.\u003c\/p\u003e\n\u003cp\u003eThe 295-253 is suited for measuring wall thickness of tubes, checking the radius of concave bores, and inspecting curved components in manufacturing and metrology applications. It is applicable in machine shops, fabrication facilities, and quality assurance settings where contact geometry on non-flat surfaces demands a ball anvil configuration. The included plastic case provides protected storage during transport and bench storage. Both the anvil and spindle are constructed from steel. The instrument carries an IP65 ingress protection rating, making it suitable for use in environments with coolant mist or light fluid exposure common in production machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall anvil design enables accurate single-point contact on curved and convex surfaces\u003c\/li\u003e\n  \u003cli\u003eResolution of 0.00005 inches (0.001 mm) for high-precision dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at 0.00015 inches per TUV certification\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers consistent measuring force to eliminate operator variation\u003c\/li\u003e\n  \u003cli\u003eIP65 ingress protection rating resists coolant mist and light fluid exposure\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish minimizes glare and provides corrosion resistance in shop conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard outside micrometer replacement or addition for precision inspection toolkits requiring ball anvil contact geometry across a 0 to 1 inch measurement range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation. Calibration should be verified against a known standard before use, following shop metrology procedures. Store in the included plastic case to protect the measuring faces from damage.
