210 Products

Also known as rafter squares, these have a 0° to 90° scale for measuring angles.

Squares

High-Accuracy Squares

Ensure reliable, repeatable angles.

High-Accuracy Square Sets

Ensure reliable, repeatable angles.

Squares with Graduations on Both Blades

Also known as carpenters’ and framing squares, these have graduations on both blades for horizontal and vertical measurements.

Laser Squares

Lay out machine tables and work stations at precise right angles. This laser generates two red lines that form a 90° angle.

Squares

Also known as try squares, these are square inside and out for checking and marking angles.

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.

Squares with Adjustable Blade

Measure and mark material exactly where you need to with a sliding blade.

Combination Squares

Replace your try square, miter square, depth gauge, marking gauge, 90° level, ruler, and scriber with one tool.

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 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.

High-Accuracy Combination Squares

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level.

Scratch-Resistant High-Accuracy Combination Squares

A titanium coating protects the blade against scratches and wear.

High-Accuracy Combination Square Blades

Blades are for use with High-Accuracy Combination Square Heads.

High-Accuracy Combination Square Heads

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

Pipefitters' Squares

Pipe fitting sizes and welding charts are shown on this square in wear-resistant etched markings.

Protractors

Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle.

Digital Protractors with Level

These tools have front and back digital displays, as well as horizontal and vertical vials.

Digital Protractors

These magnetic tools have one digital display and a lock to hold the arms in position.

Starrett Protractors with Adjustable Arms

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

Protractors with Adjustable Arms

Set bevels and measure angles. Also known as bevel protractors, these have an adjustable arm.

Protractors
