Measuring and Inspecting

Pipe Size Chart/Rulers

Pipe Size Chart/Rulers

Curl around pipe to gauge its size, measure its diameter, or mark lines

Thread Size Identifiers

Thread Size Identifiers

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

Tape Measures

Standard, long, center-finding, and flexible tape measures

Diameter Identifiers

Diameter Identifiers

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

Calipers

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

Rulers

Horizontal, vertical, circumference, center-finding, and pica rulers

Pipe Size Measuring Kits

Pipe Size Measuring Kits

Connect to pipe and fittings to determine their size without additional measuring tools

Angle Indicators

Angle Indicators

Align pipe and other equipment by measuring angle, level, or tilt

Bore Gauges

Insert into a hole and expand the contacts to measure diameter

Plug Gauges

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

Bore Gauge Heads

Bore Gauge Heads

Swap the head on your Mitutoyo electronic bore gauge for one with a different measuring range

Tap and Drill Chart/Rulers

Tap and Drill Chart/Rulers

Reference tap and drill sizes, measure in inches, and convert to decimals with one tool

Staff Gauges

Typically mounted to walls and tanks for measuring the level of liquids, such as water, fuel, and oil

Precision Measuring Tool Sets

Precision Measuring Tool Sets

Multiple precision measuring tools in one convenient case

Squares

Check 90° angles during layout work with combination, angle, or pipefitters' squares

Combination Square Heads

Combination Square Heads

Attach combination square blades to form a combination square

Outside Micrometers

Outside Micrometers

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

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

Countersink Gauges

Countersink Gauges

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

Inside/Outside Diameter Gauges

Inside/Outside Diameter Gauges

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

Center Finders

Line up your drill with the center of round bars and pipe

Center Punch/Angle Indicators

Center Punch/Angle Indicators

Find the center of pipe and other parts and determine setup angles on milling machines and grinders

Level Mounts

Strap to nonmagnetic surfaces to attach a magnetic level

Optical Comparators

Optical Comparators

Magnify your part to check for dimensional accuracy and surface defects

Laser Levels

Project level references onto surfaces when installing drop ceilings, pipe, or conveyors

Leveling Rods

Use with sight levels to estimate the distance between you and a given object

Levels

Ensure surfaces are completely horizontal or vertical

Communication

Reference Charts

Reference Charts

Check decimal equivalents, drill sizes, or specifications for socket screws

Reference Books

Reference Books

Keep industrial information, regulations, and processes on hand
