Gage blocks of this type serve as dimensional reference standards used to calibrate measuring instruments, set up machine tools, and verify workpiece tolerances on the shop floor or in a metrology lab. This block includes NIST certification, providing traceability to national standards of measurement. It is primarily used by machinists, quality control technicians, and calibration specialists who require a reliable, repeatable reference for precision measurement work.\u003c\/p\u003e\n\u003cp\u003eGrade AS-1 gage blocks are suited for inspection and calibration applications where high dimensional accuracy is required. This block is appropriate for use in manufacturing environments, tool rooms, and quality labs. It can be used individually or wrung together with other blocks in a set to build up specific dimensions. Typical applications include setting comparators, checking micrometers, and establishing reference dimensions during setup operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy for inspection and calibration-grade dimensional reference\u003c\/li\u003e\n  \u003cli\u003eNominal size of 0.114 inches for precise stack and single-block measurement applications\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable certification included for documented measurement traceability\u003c\/li\u003e\n  \u003cli\u003eRectangular steel construction for durability and consistent wringing performance\u003c\/li\u003e\n  \u003cli\u003eSingle-block packaging suitable for replacing or supplementing an existing gage block set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard rectangular gage block for use with conventional gage block accessories including holders, jaws, and scribing points compatible with Grade AS-1 steel blocks.
