Custom Cylindrical Ring Gages. Class XX, X, Y, Z or ZZ; Direction of Tolerance: GO (Minus Tolerance) NoGo (Plus Tolerance) Master (Bilateral Tolerance) Materials: Tool Steel 60/65 Rc ; Chrome 70/72 Rc ; Carbide 90/92 Ra; Diameter Range: Steel & Chrome: .0600" (1.52mm) - 12.2600" (311.40mm) Carbide: .0600" (1.52mm) - 1.5100" (38.35mm)

Cylindrical plain ring gages may be used as a pass / fail inspection tool to inspect outside diameters. If the Go ring fits and the No-Go does not, the part outside diameter is in tolerance. The selection of the Go and No-Go gage diameters and the tolerances can be challenging.

Vermont Gage has the capabilities to produce a wide variety of custom thread gages. We manufacture, ACME, STUB ACME, Buttress and other thread forms to ANSI, ASME or to other standards. Depth Notches, Blunt Starts and Multiple Start threads may be manufactured as well.

Custom Gage Sets and inserts. Custom inserts and sets made to fit your gages of varying sizes and designs. Details

PURPOSE PIN GAGES Make quick and accurate measurements with Vermont Gage Pin Gages. Measure hole sizes. Calculate distances between holes. Gage slot widths. Check loca ons. Use for Go/ NoGo gaging. Size in micrometers and snap gages. These economical gages give you added wear life, unlike closer tolerance gages available on the market today.

The 10% Rule is intended to assist in the selection of the tolerance for Go & No-Go gages. The premise is; if you surrender 10% of the total product tolerance to the gages, you will pass 90% of your product tolerance 100% of the time, if the Go fits and the No-Go does not.
