Spi 15-020-1 Steel Gage Block 0.106 in Grade AS-1

Product Description

The SPI 15-020-1 is a rectangular steel gage block measuring 0.106 inches, manufactured to Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, verify dimensional tolerances, and set up inspection equipment. This block includes NIST certification, establishing a traceable accuracy standard essential for quality control and metrology applications. Grade AS-1 denotes a high level of dimensional accuracy, making this block suitable for tool room, inspection, and calibration work where precise length references are required. Machinists, toolmakers, metrologists, and quality control technicians are the primary users.

This gage block is intended for use in machine shops, inspection rooms, and manufacturing facilities where accurate dimensional measurement is critical. It serves as a length reference for setting height gages, comparators, and other precision measuring instruments. The 0.106-inch size is a standard increment used in combination sets to build up virtually any required dimension within tolerance. Single blocks like this are also used as individual reference standards for specific inspection setups.

Key Features

• Grade AS-1 accuracy for high-precision calibration and inspection applications
• Includes NIST certification for traceable measurement standards compliance
• Steel construction provides durability and dimensional stability over time
• Rectangular form compatible with standard gage block accessories and holders
• 0.106-inch nominal size supports combination set builds and standalone reference use

Compatibility

Designed as an individual rectangular gage block for use with standard gage block sets, holders, and accessories conforming to ASME B89.1.9 gage block specifications.

Installation Notes

Gage blocks are handled and wrung together by metrology technicians or toolmakers in controlled environments. Store blocks in their protective case and apply a light film of oil or appropriate preservative when not in use to prevent corrosion. Wring blocks together with a clean, lateral sliding motion rather than pressing face-to-face to avoid surface damage. Follow facility calibration procedures and applicable ASME B89.1.9 standards for proper use and recalibration intervals.
