Measuring and Inspecting

Variance Indicators

Variance Indicators

Identify small dimensional differences when checking part quality and alignment

Thread Size Identifiers

Thread Size Identifiers

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

Depth Gauges

Reach into slots, counterbores, and other holes to measure depth

Calipers

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

Outside Micrometers

Outside Micrometers

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

Variance Indicator Contact Points

Variance Indicator Contact Points

Attach to your variance indicator to make contact with the workpiece being measured

Depth Micrometers

Depth Micrometers

Measure slots, counterbores, and other holes more precisely than depth gauges

Height Gauges

Measure an object's height and mark workpieces for machining

Rulers

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

Micrometer Heads

Micrometer Heads

Mount on jigs, fixtures, and machine tools to position equipment and measure length

Inside Hole Calipers

Inside Hole Calipers

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

Thickness Gauges

Thickness Gauges

Move the thumb lever to quickly check the thickness of flat stock, pipe, or tubing

Inside Hole Micrometers

Inside Hole Micrometers

Find the inside diameter of cylinders and rings

Squares

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

Feeler Gauges

Check gaps and alignment between machine parts and other surfaces

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

Staff Gauges

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

Chamfer Gauges

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

Precision Measuring Tool Kits

Precision Measuring Tool Kits

Multiple precision measuring tools in one convenient case

Calibration Rods

Calibration Rods

Check and set micrometers and other measuring tools

Liquid-Level Tape Measures

Liquid-Level Tape Measures

Lower into deep containers, such as tanks, to check the level of oil and other fluids

Combination Square Blades

Combination Square Blades

Connect to a combination square head to create a combination square

Threaded Hole Location Gauges

Threaded Hole Location Gauges

Pinpoint the true center of threaded holes to precisely align and measure parts

Squareness Gauges

Squareness Gauges

Check frames and machined parts to see if they are leaning or uneven

Parallel Rules

Draw parallel lines, as well as circles, arcs, and angles

Transfer Punches

Transfer Punches

Mark the center of an existing hole onto a separate workpiece

Straightedges

Draw straight lines and check the straightness of surfaces

Layout Compasses

Layout Compasses

Draw circles and transfer distance measurements

Position Indicators

Position Indicators

Track components on rotating spindles or lead screws to help adjust machinery quickly and precisely

Load Cells

Measure forces and send them to computers to monitor and trigger actions in machinery

Counters

Record and display the number of times events or processes occur

Scales

Bench-top, hanging, floor, and conveyor scales

Chemistry Meters

Chemistry Meters

Take water-chemistry measurements more precisely than test strips and swabs

Fabricating and Machining
