Use these metric Class X plug gauges for precision go/no-go measuring of hole sizes and depths, checking hole location and distance, and setting micrometers. They’re also called pin gauges.
A black-oxide treatment on these go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—use them to check to minimum hole diameter.
The black-oxide treatment on these no-go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—they help you check the maximum hole diameter.
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.
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.
To indicate when you need to calibrate or replace the gauges in these sets, gauges have a black-oxide treatment that shows wear patterns.
Take precision go/no-go measurements of hole sizes and depths, check hole location and distance, and set micrometers.
To measure thickness in areas where standard feeler gauges don’t fit, these sets have leaves with narrow ends.
Leaves have narrow ends to measure thickness where standard feeler gauges can’t fit.
A certificate of calibration traceable to NIST states that these sets have passed a test for accuracy.
Width markings on the leaves let you check diameters and widths.
These sets combine a wire gauge, a tapered-width feeler gauge, and a set of feeler gauges for tight spots in one tool.
With leaves that are color coded based on thickness, you can read your measurements at a glance.
To keep the set complete, gauge leaves are riveted together in a fan design that folds up for portability.
Check gaps, alignment, and narrow slots with these feeler gauge sets that include leaves in a variety of thicknesses riveted together in a fan design.
To ensure accurate readings, these sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.
Since each thickness is a different color, there’s no need to read the feeler gauge to tell your measurement.
Use these feeler gauge assortments to check gaps, alignment, and narrow slots.
Replace an entire feeler gauge set with one of these tapered gauges that lets you check a range of thicknesses.
Gauges are 12” long and have finished ends marked with thickness.
Cut to your desired length.
A certificate of calibration traceable to NIST states that this gauge has passed a test for accuracy.
Check a range of thicknesses with a single tapered gauge.
Squish these tiny plastic strips between two components to measure the clearance between them. Once compressed, match the widest part of the flattened strip to the markings on the paper gauge. Each marking on the gauge corresponds to a different clearance measurement.
