Value Collection 630-73186 Square Gage Block 0.18 in Grade 0

Product Description

The VALUE COLLECTION 630-73186 is a square steel gage block measuring 0.18 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify part dimensions, and set up comparators and height gages. This block is made from steel and meets the dimensional and flatness requirements of Grade 0, making it suitable for applications that demand high measurement accuracy. Metrology technicians, toolroom machinists, and quality control inspectors are the primary users of this type of precision reference standard.

This gage block is appropriate for use in toolrooms, quality labs, and manufacturing environments where dimensional verification is required. The square profile allows for stacking and wringing with other gage blocks to build up precise measurement combinations. At 0.18 inches, this block fits into standard gage block sets as a specific increment for dimensional reference work. It is sold individually, making it a practical replacement for a single worn or damaged block in an existing set.

Key Features

• Grade 0 accuracy for high-precision measurement and calibration applications
• Square steel construction provides durability and consistent surface flatness
• 0.18-inch nominal size for precise dimensional reference
• Compatible with wringing technique to combine with other gage blocks for custom stack dimensions
• Sold as a single unit for targeted replacement or supplemental use

Compatibility

Designed as an OEM-style replacement or supplemental reference standard compatible with standard square gage block sets used in toolroom and metrology applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and toolroom machinists following established measurement standards such as ASME B89.1.9. Clean block surfaces thoroughly before use to prevent contamination that can affect accuracy. When wringing blocks together, apply gentle lateral sliding pressure rather than forcing blocks apart after assembly. Store in a protective case away from moisture, vibration, and temperature extremes to maintain calibrated accuracy.
