Staff Gauges

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

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

Squares

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

Depth Gauges

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

Diameter Identifiers

Diameter Identifiers

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

OSHA/ANSI Safety Gauges

OSHA/ANSI Safety Gauges

Confirm gaps in bench grinders and machine guards meet OSHA and ANSI safety requirements

Radius Gauges

Check convex and concave radii of tools, patterns, and dies

Liquid-Level Tape Measures

Liquid-Level Tape Measures

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

Depth Micrometers

Depth Micrometers

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

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

Test objects to see how much tension and compression force they can bear

Load Cells

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

Torque Gauges

Test the accuracy of torque wrenches and screwdrivers

Torque Sensors

Convert manually applied torque into an electrical signal that you can measure and record

Levels

Ensure surfaces are completely horizontal or vertical

Level Mounts

Strap to nonmagnetic surfaces to attach a magnetic level

Surface Finish Gauges

Surface Finish Gauges

Compare your surface to the swatches to see if you’ve achieved the desired finish

Hardness Calibration Test Blocks
