Value Collection 636-6000 Round Steel Gage Block 0.6 in Grade B

Product Description

The VALUE COLLECTION 636-6000 is a round steel gage block manufactured to Grade B accuracy standards. Gage blocks are precision-ground reference standards used to verify, calibrate, and set measuring instruments to known dimensional tolerances. This block measures 0.6 inches and is constructed from steel, delivering the dimensional stability required for reliable shop-floor measurement. Grade B accuracy designates this block for general inspection and measurement work where high-precision laboratory-grade tolerances are not required. Machinists, tool-and-die makers, and quality control technicians use gage blocks as master references for calipers, micrometers, height gages, and comparators.

This round gage block is suited for use in machine shops, fabrication facilities, and inspection departments where repeatable dimensional reference is needed. Its round form factor allows it to be used independently or wrung with compatible flat gage blocks depending on the application. It is appropriate for general production inspection, tool setup, and instrument calibration tasks in both light manufacturing and heavy industrial environments.

Key Features

• Grade B accuracy for general inspection and measurement applications
• 0.6-inch nominal size with five-decimal precision designation (0.60000 inches)
• Steel construction for dimensional stability and durability in shop environments
• Round form factor suitable for standalone reference use
• Single-piece packaging for individual procurement flexibility

Compatibility

Designed as a standard round gage block reference for use with precision measuring instruments including micrometers, comparators, and height gages in general inspection and calibration applications.

Installation Notes

Gage blocks require careful handling to maintain surface integrity and accuracy. Store blocks in a protective case away from moisture and contaminants to prevent corrosion of the steel surfaces. Clean contact faces before use and allow blocks to reach ambient temperature before taking measurements, as thermal expansion can affect readings. Wringing surfaces together requires clean, flat, burr-free faces — inspect for damage before each use.
