All gauges have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off.

Connectable extension rods allow you to measure depths.

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

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

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

Use extension rods in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections.

Connect continuous segments to create a ruler up to 10 ft. long.

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Measure volume in gallons without calculations.

Permanently mount these rulers on machines, tanks, and walls to measure heights and depths.

Measurements are printed from top to bottom for measuring heights and depths.

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.

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.

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