Size Checking

Plug Gauge Handles

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

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.

Ball-End Plug Gauges with Handle

Check the true diameter of holes, even if they’re bent or curved. The thin stem on these gauges flexes to reach features deep inside holes and cavities.

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.

Threaded Plug Gauges with
Handle for Pipe Threads

Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly.

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.

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.

Ring Gauge Holders

Often used with go and no-go ring gauges, these holders keep two ring gauges still for quick, repeat measuring.

Threaded Ring Gauge Holders

Join two ring gauges with different sizes to quickly check if threads are within tolerance. Secure your gauges to these holders with the included fasteners.
