Dimensional Measuring

Starrett High-Accuracy Rulers

Also known as machinists’ rules, these rulers ensure reliable, repeatable measurements.

Starrett Certified High-Accuracy Rulers

Ensure reliable, repeatable measurements with these rulers.

Starrett High-Accuracy Rulers with Hook

A reversible, removable hook grabs the edge of an object for easy alignment.

Certified Tape Measures

Ensure accurate measurements with certified tape measures.

Starrett Certified Long Tape Measures

These reliable tape measures include a calibration certificate traceable to NIST stating they have passed a test for accuracy.

Starrett Depth Gauges

Reach deep into small holes and slots for precise depth measurements.

Starrett Depth Micrometers

Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths.

Starrett Depth Micrometers
with Calibration Certificate

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Angle Measuring

Starrett High-Accuracy Combination Square Blades

Use these blades with Starrett High-Accuracy Combination Square Heads. They meet Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Starrett High-Accuracy Combination Squares

Replace your try square, miter square, depth gauge, height gauge, center-point finder, and level. The blade on these squares meets Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Starrett High-Accuracy Combination Square Heads

Attach to Starrett High-Accuracy Combination Square Blades with the included lockbolts.

Starrett High-Accuracy Squares

These squares meet Fed. Spec. GGG-S-656-E, which establishes uniform standards for square accuracy to ensure reliable, repeatable angles.

Starrett Protractors with Graduated Arm

Measure angles and dimensions with one tool.

Starrett Protractors with Adjustable Arms

Also known as bevel protractors, set bevels and measure angles with the adjustable arm.

Angle Identifiers

These gauges have 18 leaves that swing out when you want to quickly check an angle. They're more convenient than a protractor when identifying 45° and smaller angles.

Levels

Starrett Pocket Levels

Carry these compact levels with you.

Starrett Precision Levels

With a precision-machined leveling surface and highly sensitive vial, this level provides superior accuracy.

Starrett Precision Levels with Calibration Certificate

These levels come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Starrett Multi-Plane Precision
Levels with Calibration Certificate
