Value Collection 630-71006 Square Steel Gage Block 1 in Grade 0

Product Description

The VALUE COLLECTION 630-71006 is a 1-inch square steel gage block graded to Grade 0 accuracy standards and supplied with NIST certification. Gage blocks are precision-ground reference standards used to verify, calibrate, and set measurement instruments in machining, inspection, and quality-control environments. The Grade 0 classification indicates a high level of dimensional accuracy, making this block suitable for calibration lab use and precision inspection work. At 0.45 pounds, it is a solid, single-block unit appropriate for bench and instrument use by metrology technicians and machine shop inspectors.

This gage block is suited for use in machine shops, metrology labs, manufacturing inspection departments, and tool-and-die operations. It serves as a dimensional reference standard for calibrating micrometers, height gages, comparators, and similar precision instruments. The included NIST certification documents traceability to national measurement standards, which is required in many quality management systems including ISO 9001-compliant inspection processes. The 1.00000-inch nominal size makes it a commonly needed block for establishing baseline measurements.

Key Features

• Grade 0 accuracy classification for precision calibration and inspection use
• NIST certification included for documented measurement traceability
• Steel construction provides durability and dimensional stability
• 1.00000-inch nominal size suitable for a wide range of calibration tasks
• Square block form factor for stable contact with reference surfaces

Compatibility

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

Installation Notes

Gage blocks are handled and used by metrology technicians and precision inspection personnel. Keep block surfaces clean and free of oils, burrs, and debris before use to ensure accurate measurement contact. Store in the supplied case when not in use to prevent surface damage and corrosion. Do not drop or stack blocks on abrasive surfaces, as surface damage will affect dimensional accuracy and invalidate certification.
