Measuring and Inspecting

Diameter Identifiers

Diameter Identifiers

Tighten the strap around rods, drill bits, and other small items to measure outer diameter

Thread Size Identifiers

Thread Size Identifiers

Confirm your fastener's thread size, pitch, or threads per inch

Go/No-Go Outside Diameter Gauges

Go/No-Go Outside Diameter Gauges

Snap on rods and shafts to check if their outside diameters are within tolerance

Plug Gauges

Verify the diameter or threads of machined holes in finished parts; also called pin gauges

Bore Gauges

Insert into a hole and expand the contacts to measure diameter

Inside Hole Micrometers

Inside Hole Micrometers

Find the inside diameter of cylinders and rings

Inside Hole Calipers

Inside Hole Calipers

Measure hard-to-reach areas, such as internal grooves and slots

Outside Micrometers

Outside Micrometers

Apply even pressure to objects to measure thickness more precisely than thickness gauges

Calipers

Take inside, outside, and depth measurements with more precision than a ruler

Inside/Outside Diameter Gauges

Inside/Outside Diameter Gauges

Mount your variance indicator to measure the diameter of rims, grooves, and shallow holes

Gauge Blocks

Confirm dies, fixtures, and other workpieces meet precise tolerances and calibrate measuring tools

Feeler Gauges

Check gaps and alignment between machine parts and other surfaces

Micrometer Speeder Knobs

Micrometer Speeder Knobs

Color code micrometers by calibration date, precision, or other criteria

Countersink Gauges

Countersink Gauges

Catch sizing errors in countersunk holes to keep fasteners from protruding and creating weak points

Height Gauges

Measure an object's height and mark workpieces for machining

Step Gauges

Check step height, gap width, and distance between slots to make sure machine and engine parts align

Chamfer Gauges

Check the diameter of chamfered edges to make sure they're within tolerance

Optical Comparators

Optical Comparators

Magnify your part to check for dimensional accuracy and surface defects
