Plug Gauges with Handle

Take go and no-go measurements with the same tool. These gauges have a go gauge on one end, a no-go gauge on the other end, and a handle with bushings.

Plug Gauge Handles

Add a handle to hold your plug gauge. No need for bushings—one handle fits a range of plug gauge sizes.

Go/No-Go Threaded Plug Gauges with Handle

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges.

Go/No-Go Left-Hand Threaded
Plug Gauges with Handle

A go and no-go gauge in one, these gauges check that left-hand threads fall within tolerance.

Go/No-Go Helical Insert Threaded
Plug Gauges with Handle

Check that holes tapped for helical threads are within tolerance. To speed up tests, these gauges have a go gauge on one end and a no-go gauge on the other.

Acme Threaded Plug Gauges with Handle

Determine if lead nuts, screw collars, and other parts with internal Acme threads are within tolerance. These gauges are attached to a handle to help you quickly thread or unthread them.

Threaded Plug Gauge Handles

Speed up checking thread tolerances by threading a go gauge on one end of these handles and a no-go gauge on the other.

Battery-Powered Pistol-Grip
Drivers for Threaded Plug Gauges

Test thread tolerance in seconds. A time-saver for high-volume work, these drivers quickly thread gauges in and out of holes for you—just pull the trigger.

Go/No-Go Hex Plug Gauges with Handle

Confirm hex drives on socket head screws are within tolerance.
