Value Collection 630-33156 Steel Gage Block 0.15 in AS-1

Product Description

The VALUE COLLECTION 630-33156 is a rectangular steel gage block measuring 0.15 inches, manufactured to Grade AS-1 accuracy and supplied with NIST certification. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify tolerances in precision machining and inspection environments. The AS-1 grade designation indicates a high level of dimensional accuracy suitable for metrology labs, tool rooms, and quality control applications. Each block ships individually and is intended for use by machinists, quality engineers, and calibration technicians who require traceable measurement references.

This gage block is suited for use in machine shops, manufacturing facilities, and inspection labs where precise linear measurement is required. The 0.15-inch size fills a specific incremental value in a gage block set or serves as a standalone reference for setups requiring that dimension. It is appropriate for both production-floor measurement verification and laboratory-grade calibration work. The included NIST certification provides traceability documentation for regulated or quality-system-governed environments.

Key Features

• Grade AS-1 accuracy for reliable dimensional reference in precision measurement applications
• NIST certification included, providing traceable calibration documentation
• Steel construction for durability and dimensional stability under typical shop conditions
• 0.15-inch nominal size for use as a single reference block or as part of a build-up set
• Rectangular form factor compatible with standard wringing and stacking practices

Compatibility

Designed as a standard rectangular gage block for use with comparators, height gages, and other precision measurement instruments that accept individual or wrung gage block references.

Installation Notes

Gage blocks should be handled by metrology technicians or qualified machinists familiar with proper wringing technique and block care. Clean mating surfaces thoroughly before wringing to prevent surface damage. Store blocks in a protective case away from humidity and temperature extremes to preserve dimensional integrity. Do not drop or stack blocks without proper support, as steel gage blocks are susceptible to surface damage that affects accuracy.
