This is a new factory-sealed bag of 1,000 Bal-Tec precision gage balls, item number 000440000AH, manufactured by Bal-tec Division (Los Angeles, CA) to ABMA Grade 25 tolerances. The balls are 0.044040 inches in diameter and made from carbon steel (C/S), certified under lot number 117065 / cert 0816517 as read directly from the label. ABMA Grade 25 specifies a ball diameter variation (VBD) of ≤25 millionths of an inch (0.000025 in) and a lot diameter variation (VDL) of ≤25 millionths of an inch, making these suitable for use as check balls in hydraulic valves, fuel injection components, ball screws, bearing assemblies, and precision gauging fixtures. At approximately 1.12 mm in diameter, these micro-balls are commonly used in check valve seats, orifice calibration, and precision instrumentation where tight sphericity control is required.
