Value Collection 630-21336 Steel Gage Block 0.133 in Grade 0

Product Description

The VALUE COLLECTION 630-21336 is a rectangular steel gage block ground to a nominal size of 0.133 inches and manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on machined parts. This block includes NIST certification, confirming traceability to national measurement standards. Grade 0 blocks deliver tighter tolerances than Grade 1 or Grade 2 blocks, making them suitable for calibration lab use and high-precision inspection work. Machinists, quality technicians, and metrologists rely on certified gage blocks as the foundation of any traceable measurement program.

This gage block is used in precision measurement environments including machine shops, quality assurance labs, and tool rooms. It is appropriate for both incoming inspection and in-process measurement tasks where dimensional accuracy is critical. The NIST certification documentation shipped with the block supports audit requirements and ISO-compliant calibration programs. Single-block packaging makes it a practical replacement or addition to an existing gage block set when one size is worn, damaged, or lost.

Key Features

• Nominal size of 0.133 inches with Grade 0 accuracy tolerance
• Steel construction for durability and long-term dimensional stability
• Includes NIST certification for traceable measurement compliance
• Rectangular form compatible with standard gage block accessories and holders
• Sold individually, allowing targeted replacement within an existing set

Compatibility

Designed as a standard rectangular gage block for use with conventional gage block holders, comparator stands, and wringing fixtures that accept steel blocks in this size range.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality assurance personnel, not field tradespeople. Before use, clean block surfaces with an appropriate gage block cleaning solution to remove oils and contaminants that affect wringing and accuracy. Store the block in its protective case when not in use to prevent corrosion and surface damage. Do not drop or strike the block against hard surfaces, as this can alter the lapped faces and invalidate the certification.
