Value Collection 630-31026 Steel Gage Block 0.102 in Grade AS-1

Product Description

The VALUE COLLECTION 630-31026 is a rectangular steel gage block ground to a nominal size of 0.102 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 machining and inspection environments. This block includes NIST certification documentation, confirming that its dimensions have been traceable to national measurement standards. Grade AS-1 indicates a high level of dimensional accuracy suitable for toolroom and inspection use. Machinists, quality technicians, and calibration specialists are the primary users of this type of reference standard.

This gage block is suited for toolroom inspection, incoming quality control, and calibration of calipers, micrometers, and height gages in both production and laboratory settings. Its rectangular form factor allows it to be wrung with other steel gage blocks to build up compound dimensions. It is appropriate for use wherever a traceable, certified reference standard is required in a precision measurement workflow.

Key Features

• Nominal size of 0.102 inches ground to Grade AS-1 accuracy
• Steel construction for durability and dimensional stability
• Includes NIST certification for measurement traceability
• Rectangular form compatible with standard wringing techniques
• Single-piece packaging for individual block replacement or set supplementing

Compatibility

Designed as an OEM-style replacement or supplemental reference standard for use with rectangular steel gage block sets requiring a 0.102-inch block in Grade AS-1.

Installation Notes

Gage blocks are handled and stored by metrology technicians or toolroom personnel, not installed in the traditional sense. Before use, clean mating surfaces with a lint-free cloth and an appropriate solvent to remove oils and debris. When wringing blocks together, use a slow, overlapping sliding motion to achieve proper adhesion. Store in the provided case away from temperature extremes and corrosive environments to maintain certification validity.
