Measuring 20 mm in diameter, this ball meets Grade 25 accuracy standards and is AFBMA certified, making it suitable for use in gauging fixtures, go\/no-go gauges, comparators, and other precision inspection tooling. The hardened chrome steel construction provides consistent geometry and surface finish critical to repeatable measurement results. Each package contains 2 balls. Installers, metrologists, and quality control technicians working with calibrated measurement equipment are the primary users.\u003c\/p\u003e\u003cp\u003eThis gage ball is designed for use in precision measurement and quality control environments where tight dimensional tolerances must be verified. Typical applications include fixture gauging, bore gauging, and reference standards in machine shops, manufacturing facilities, and inspection labs. The 20 mm diameter and Grade 25 accuracy classification make this ball appropriate for applications requiring high repeatability and low deviation from nominal size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 mm diameter for precise dimensional gauging applications\u003c\/li\u003e\n\u003cli\u003eGrade 25 accuracy per AFBMA standards ensures tight tolerance conformance\u003c\/li\u003e\n\u003cli\u003eHardened chrome steel construction for durability and surface consistency\u003c\/li\u003e\n\u003cli\u003eAFBMA certified for use in calibrated measurement workflows\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 2 balls per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard precision gauging fixtures, comparators, and inspection tooling that accept 20 mm diameter gage balls conforming to AFBMA Grade 25 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGage balls should be handled with clean, dry gloves or lint-free cloths to prevent surface contamination that can affect measurement accuracy. Store in a protective case away from moisture and debris when not in use. Verify that the receiving fixture or gauge is rated for the ball diameter before use.
