Value Collection 630-31106 Steel Gage Block 0.11 in Grade AS-1

Product Description

The VALUE COLLECTION 630-31106 is a rectangular steel gage block ground to a nominal size of 0.11 inches and certified to Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machine shops, metrology labs, and manufacturing facilities. This block includes NIST certification, providing a traceable accuracy record required by many quality management systems. Grade AS-1 represents a high-accuracy classification suitable for tool room and inspection-grade measurement work. The steel construction offers durability and wringing compatibility with other steel gage blocks.

This gage block is suited for use in dimensional inspection, calibration of micrometers and calipers, machine setup, and surface plate layout work. It is appropriate for both shop floor and controlled metrology environments. The 0.11-inch nominal size makes it a standard increment block for building stacked combinations. Machinists, metrologists, toolmakers, and quality control technicians are the primary users in both job shop and production inspection settings.

Key Features

• Grade AS-1 accuracy for tool room and inspection-grade dimensional verification
• Steel construction for durability and wringing compatibility with steel block sets
• 0.11-inch nominal size for use as a single reference or within stacked combinations
• Includes NIST certification for traceable calibration documentation
• Rectangle geometry with lapped and polished faces for reliable wringing adhesion

Compatibility

Designed as an OEM-style individual gage block compatible with standard steel rectangular gage block sets used in dimensional metrology and machine shop inspection applications.

Installation Notes

Gage blocks should be handled by a trained metrologist or toolroom technician familiar with proper wringing technique and surface protection practices. Store blocks in a protective case away from moisture and contaminants to prevent corrosion on lapped faces. Clean faces thoroughly with a lint-free cloth and appropriate solvent before and after use. Do not drop or slide blocks across hard surfaces, as this will damage the lapped reference faces and compromise calibration accuracy.
