Value Collection 636-1050 Round Steel Gage Block 0.105 in Grade B

Product Description

The VALUE COLLECTION 636-1050 is a round steel gage block ground to a nominal size of 0.105 inches and certified to Grade B accuracy. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set up comparators, and verify machined part tolerances on the shop floor. Grade B accuracy suits general inspection and tool-room work where tight calibration traceability is required but ultra-precision Grade AS or Grade K tolerances are not specified. Machinists, quality control technicians, and tool-and-die tradespeople use these blocks as part of a precision measurement program.

This block is suited for use in machine shops, fabrication facilities, and inspection departments. It functions as a go-to reference for setting dial indicators, height gages, and snap gages to a known 0.105-inch dimension. Grade B blocks are appropriate for production-floor inspection tasks and general metrology applications where a traceable size standard is needed without the cost of a higher-grade set.

Key Features

• Nominal size of 0.105 inches for precise dimensional referencing
• Grade B accuracy rating suitable for general inspection and tool-room use
• Steel construction for durability and resistance to wear during repeated handling
• Round form factor for compatibility with standard gage block accessories and holders
• Single-block packaging allows replacement or supplementation of existing gage block sets

Compatibility

Designed as an OEM-style replacement or supplemental block compatible with standard round gage block holders and sets used in general metrology and machine-shop inspection applications.

Installation Notes

Gage blocks should be handled by qualified metrology or machining personnel familiar with wringing technique and proper block care. Before use, clean contact surfaces with a lint-free cloth and an appropriate gage oil or cleaning solvent to remove debris and prevent surface corrosion. Store blocks in a protective case away from temperature extremes to maintain dimensional stability. Do not drop or strike blocks against hard surfaces, as impact can damage lapped faces and compromise accuracy.
