Plug Gauges for Inside Diameters

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.

Target-Size Plug Gauge Sets

Get your choice of one target-size gauge with 12 larger gauges and 12 smaller gauges, graduated in 0.0001”. Use these sets to measure hole sizes and depths, check hole locations and distance, and set micrometers.

Plug Gauge Sets

Keep dozens of plug gauges on hand to check a range of hole sizes. You’ll often hear them called pin gauges.

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.

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 Hex Plug Gauges with Handle

Confirm hex drives on socket head screws are within tolerance.

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.
