Value Collection 630-73006 Steel Gage Block 3 in Grade 0

Product Description

The VALUE COLLECTION 630-73006 is a square steel gage block sized at 3.00000 inches, manufactured to Grade 0 accuracy standards. Gage blocks are precision reference tools used to calibrate measuring instruments, verify dimensional accuracy, and set comparators in machining and inspection environments. This block ships with NIST certification, confirming its dimensional accuracy has been verified against national measurement standards. Grade 0 represents a high level of dimensional tolerance, making this block appropriate for applications that demand tight measurement traceability. Machinists, quality control technicians, and tool room professionals are the primary users of this type of precision reference standard.

This gage block is suited for use in machine shops, tool rooms, quality assurance labs, and manufacturing inspection stations. It is appropriate for both incoming inspection workflows and in-process dimensional verification. The 3-inch size covers a commonly referenced nominal dimension across a wide range of workholding, tooling, and fixture setups in both production and job shop environments. Its square form allows stable stacking and wringing with compatible blocks in standard gage block sets.

Key Features

• Grade 0 accuracy for high-precision dimensional reference applications
• 3.00000 inch nominal size with tight dimensional tolerance
• Includes NIST certification for measurement traceability
• Steel construction provides durability and resistance to wear during repeated use
• Square form supports wringing and stacking with compatible gage block sets

Compatibility

Designed as an OEM-style precision reference standard compatible with standard square gage block sets used in dimensional inspection and calibration applications.

Installation Notes

Gage blocks are handled and stored by quality control and metrology professionals. Before use, clean all mating surfaces with an appropriate solvent to remove oils and debris that can affect measurement accuracy. Store the block in its protective case away from temperature extremes to maintain dimensional stability. Do not drop or slide the block on hard surfaces, as impact or abrasion can compromise the lapped reference faces.
