Value Collection 630-31266 Steel Gage Block 0.126 in AS-1

Product Description

The VALUE COLLECTION 630-31266 is a rectangular steel gage block ground and lapped to Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in the metrology lab. This block measures 0.126 inches and includes NIST certification documentation, confirming the block has been measured and traceable to national standards. It is a single-piece block suited for individual stack builds or direct use as a reference dimension. Machinists, tool-and-die makers, quality technicians, and calibration specialists are the primary users.

Grade AS-1 gage blocks are a working-grade standard appropriate for general shop use, incoming inspection, and machine setup verification. A 0.126-inch block is a commonly needed size in fractional and decimal stack combinations. Typical applications include setting dial indicators and comparators to a known reference, checking fixed gauges, and establishing reference points on surface plates. This block is sold as a single unit and is suitable for adding to an existing gage block set or replacing a worn or out-of-tolerance individual block.

Key Features

Compatibility

Designed as an individual replacement or supplemental block compatible with standard rectangular gage block sets and accessories that accept Grade AS-1 steel blocks.

Installation Notes

Gage blocks are handled and stored by calibration technicians and quality control personnel, not installed in the traditional sense. Clean all mating surfaces with lint-free cloth and appropriate solvent before wringing blocks together to avoid measurement error and surface damage. Store the block in its protective case when not in use to prevent corrosion and wear. Periodic recertification intervals should follow your facility's calibration control plan.
