Product Details
This gives customers the complementary angular range to the 683-3Z: the same direct-reading internal chamfer gage, calibrated for included angles from 90° to 127°.
Choosing a Range
The 684-3Z (0–1") is the popular capacity, with 0–3/8", 0–1/2" and 1–2" also available. Select the range in the dropdown above.
683 or 684?
The two series differ only in the angle band on the dial. Use the 683 for 0–90° internal chamfers and the 684 for 90–127°. Where a print calls a specific countersink angle, a countersink gage that seats on the angular face is the correct instrument.
Calibration
