Combination Wire, Width, and Thickness Feeler Gauge Sets
These sets combine a wire gauge, a tapered-width feeler gauge, and a set of feeler gauges for tight spots in one tool. The tapered-width gauge is designed for measuring hole and slot widths and diameters. The feeler gauge leaves check the thickness of slots, gaps, and alignment; each leaf is marked with thickness. Leaves are riveted together in a fan design that folds up for portability.

Spark Plug Feeler Gauges
Keep spark plugs working efficiently. These feeler gauges slide between the electrodes to measure the gap. If the gap is incorrect, they have an adjustment tool to bend the electrode where you need it.
Wire gauges measure using different wire thicknesses.
For technical drawings and 3-D models, click on a part number.
Build-Your-Own Wire, Cable, and Cord Length Measurers
Combine a counter, feeder reel, coiler reel, and stand to create a wire, cable, and cord length measurer.
Counters measure material as you thread it through the internal wheels. These counters add and subtract. Mount them on a pedestal or floor stand (sold separately). Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.
Feeder reels hold material before it's threaded through a counter. Wind material around adjustable pins on the reel, or place spooled material on the 1/2" diameter spindle.
Coiler reels gather material once it has passed through a counter. These reels have a hand crank and collapse for storage.

Wire Length Measurers
Feed wire through the wheels inside the included counter to take measurements. The counter adds and subtracts. Wind your wire around adjustable pins on the feeder reel, or place spooled wire on the 1/2" diameter spindle. Gather it on the coiler reel once it has passed through the counter. Coiler reels have a hand crank and collapse for storage.
Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.

Economy Tension Force Gauges for Wire
Measure the tension of wire or cable. First, determine your wire’s diameter with the notches on the side of these gauges. Then, insert the wire between the two nylon rollers on the bottom and the slot on top to get a needle reading. Using the table on the handle, convert the reading into a tension measurement relative to your wire’s diameter.

Tension Force Gauges for Wire and Filament
Measure the tension of wire and filament without pausing your operation. These gauges are often used to set tension and take continuous readings in 3D printing, spooling, wire cutting, and drawing machines. They can also be used with thin wire rope, carbon fiber, and fiber-optic strands. Slide your material between the three rollers to take measurements, even in tight spaces. All include a calibration certificate traceable to NIST that states these gauges meet standards for accuracy. They include a case for storage and protection.
