Value Collection 630-4100 Steel Gage Block Set 36 Piece

Product Description

The VALUE COLLECTION 630-4100 is a 36-piece rectangular steel gage block set covering a measurement range of 0.05 to 4 inches. Built to Grade 0 accuracy standards, this set is designed for precision measurement applications in machine shops, tool rooms, calibration labs, and quality control environments. Each block is individually serialized, and the set ships with NIST traceability certification, making it suitable for documented calibration workflows. Tolerances vary by block size: 6 micro inches for 0.050-inch blocks, 5 micro inches for 0.1 to 0.4-inch blocks, 6 micro inches for 0.5 to 1-inch blocks, 8 micro inches for 2-inch blocks, and 12 micro inches for 4-inch blocks. Machinists, metrologists, and quality technicians are the primary users of this set.

This gage block set is suited for dimensional inspection, instrument calibration, and setup work across manufacturing and metrology environments. The 36-piece combination covers a practical spread of sizes for both fine and coarse measurement tasks. The NIST traceability certification supports quality management systems requiring documented measurement standards, including ISO and AS9100 programs. The individually serialized blocks allow tracking and record-keeping for each individual piece within a calibration program.

Compatibility

Designed as a general-purpose Grade 0 rectangular steel gage block set compatible with standard gage block accessories including holders, jaws, and scribers conforming to inch-series gage block tooling.

Installation Notes

Gage blocks are precision instruments and should be handled by trained metrology or machining personnel. Store blocks in their case when not in use to prevent corrosion and surface damage. Before wringing blocks together, clean all surfaces with a lint-free cloth and appropriate gauge oil or cleaning solvent. Blocks should be conditioned to room temperature before use to avoid thermal expansion errors.
