The VALUE COLLECTION 630-4050 is a 36-piece round gage block set designed for precision measurement in tool rooms, machine shops, and calibration environments. The set covers a range of 0.05 to 1 inch with a tolerance of 0.0001 inch, making it suitable for high-accuracy dimensional inspection and setup work. Step increments are organized as 15 blocks in 0.010-inch steps, 9 blocks in 0.001-inch steps, and 9 blocks in 0.100-inch steps, giving technicians flexible stacking combinations across the full range. Each set ships in a fitted carrying case for organized storage and transport.
This gage block set is used in precision machining, quality control, and metrology applications where accurate reference measurements are required. Typical users include machinists, tool and die makers, quality technicians, and calibration specialists. The set is appropriate for both shop-floor use and controlled measurement environments. The fitted case keeps blocks protected and organized between uses, which is essential for maintaining block face condition over time.
Designed as a general-purpose precision reference standard compatible with standard gage block accessories and holders used in dimensional metrology and machine shop applications.
Gage blocks are precision instruments and should be handled by qualified metrology or machining personnel. Keep block faces clean and free of debris before wringing blocks together to avoid surface damage. Store blocks in the fitted case when not in use to prevent corrosion and nicking. Follow your facility's calibration interval procedures to maintain measurement traceability.
