Value Collection 636-1800 Round Steel Gage Block 0.18 in Grade B

Product Description

The VALUE COLLECTION 636-1800 is a round steel gage block ground to a nominal size of 0.18 inches and rated to Grade B accuracy. Gage blocks are precision reference standards used to verify, calibrate, and set measuring instruments on the shop floor or in inspection environments. Grade B blocks are appropriate for general workshop and production measurement tasks where high-volume use demands a durable, cost-effective reference standard. Steel construction provides the rigidity and wear resistance required for repeated contact measurement work.

This gage block is suited for use in machine shops, manufacturing facilities, and quality control departments. It serves as a setting standard for micrometers, height gages, and comparators. Grade B tolerance makes it appropriate for production-floor inspection rather than master laboratory calibration. Machinists, quality technicians, and tool-room personnel are the primary users of individual gage blocks at this specification level.

Key Features

• Nominal size of 0.18 inches for direct dimensional reference
• Grade B accuracy rating suitable for production and workshop inspection
• Steel construction for durability and wear resistance
• Round form factor for ease of handling and single-dimension referencing

Compatibility

Designed as an individual reference standard compatible with standard gage block accessories including holders, jaws, and scribers that accept round-form gage blocks.

Installation Notes

Gage blocks are handled and stored by metrology and quality control technicians following established inspection procedures. Keep contact surfaces clean and free of burrs before wringing or stacking. Store in a protective case away from moisture and temperature extremes to preserve dimensional stability. Do not drop or impact the block, as this can alter the ground reference surfaces.
