Value Collection 636-3000 Round Steel Gage Block 0.3 in Grade B

Product Description

The VALUE COLLECTION 636-3000 is a round steel gage block used to verify, calibrate, and set precision measuring instruments in machining, inspection, and toolroom environments. Manufactured to Grade B accuracy, this block measures exactly 0.30000 inches and serves as a reliable dimensional reference for machinists, quality technicians, and metrologists. Grade B blocks meet established tolerance standards for general-purpose inspection and calibration work. The steel construction provides the durability and dimensional stability required for repeated contact with gauges, micrometers, and comparator stands. This is a single-piece block intended for individual use or integration into a larger set.

Round steel gage blocks in the 0.30000-inch size are commonly used in manufacturing and machine shop environments for direct measurement, stacking, and gauge setting applications. They are appropriate for both incoming inspection and in-process quality checks. This block suits applications where Grade B tolerances satisfy the measurement requirements, such as general production inspection rather than master-level laboratory calibration. Toolroom personnel, quality control technicians, and precision machinists are the primary users.

Key Features

• Grade B accuracy for general-purpose inspection and calibration use
• Nominal size of 0.30000 inches for precise dimensional reference
• Round profile for compatibility with gage block accessories and fixtures
• Steel construction for dimensional stability and long service life
• Single-piece format usable alone or within a larger block set

Compatibility

Designed as a standard round gage block for use with compatible gage block accessories, holders, and comparator setups that accept the 0.30000-inch nominal size in a round format.

Installation Notes

Gage blocks should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store blocks in their protective case when not in use and keep them away from abrasive surfaces or impact. Before use, inspect the measuring faces for burrs or surface damage and clean with an appropriate gage block cleaner. Calibration and storage practices should follow applicable metrology standards for your facility.
