The VALUE COLLECTION 630-31306 is a rectangular steel gage block measuring 0.13 inches, manufactured to Grade AS-1 accuracy and supplied with NIST certification. Gage blocks are precision reference standards used to calibrate and verify measuring instruments such as micrometers, calipers, and comparators. This block is machined from steel and meets AS-1 accuracy grade requirements, making it suitable for shop-floor measurement, quality control inspection, and instrument calibration work performed by machinists, metrologists, and tool room technicians.
This gage block is appropriate for use in manufacturing environments, machine shops, inspection labs, and tool rooms where traceable dimensional standards are required. The included NIST certification provides a documented chain of traceability to national measurement standards, satisfying quality system requirements under ISO 9001, AS9100, and similar frameworks. It is sold as a single block and is well suited for replacing a worn or damaged block in an existing set or supplementing a calibration standard kit.
Designed as an OEM-style replacement or supplemental block for standard rectangular steel gage block sets requiring a 0.13 inch Grade AS-1 reference standard.
Gage blocks should be handled by a qualified metrologist or trained machinist using clean, lint-free gloves to prevent contamination from skin oils and debris. Before use, inspect the gaging surfaces for burrs or corrosion and clean with an appropriate gage block solvent. Store the block in its protective case when not in use to prevent surface damage. Do not attempt to wring blocks that are dirty or damaged, as this can permanently impair the reference surface.
