Angle Meters | McMaster-Carr

The electronic sensor and the display are connected by a 4-ft. cable so you can measure angles from a distance. They can be mounted up to 200 feet apart by replacing the included cable with a longer cable length.

Angle Indicators

Magnetic-Mount Angle Indicators

Temporarily mount these indicators to a metal surface. They have four quadrants that each read any angle from 0° to 90°.

Angle Indicators

Also known as angle finders, use these to gauge the angle of any surface.

Heavy Duty Magnetic-Mount Angle Indicators

These angle indicators have a horizontal leveling vial and can measure angles between 0° and 180°.

Single-Axis Tilt Indicators

A ball inside a level tube indicates the side-to-side tilt angle.

Dual-Axis Tilt Indicators

Measure 40° front-to-back tilt in addition to side-to-side tilt.

Protractors

Protractors with Adjustable Arms

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

Starrett Protractors with Adjustable Arms

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

Protractors

Measure angles with these round protractors.

Mitutoyo Precision Protractors

Precisely measure angles on molds and jigs.

Precision Protractors

Take precise measurements with this protractor.

Adhesive-Back Protractor Dials

Mount on any flat surface.

Starrett Protractors with Graduated Arm

Measure angles and dimensions with one tool.

Protractors with Graduated Arm

Use these protractors to measure angles and dimensions.

Pocket-Size Protractors

Small enough to fit in your pocket, this versatile tool measures angles and dimensions and has a center finder.

Long-Arm Protractors

Handle big jobs such as sheet metal fabricating and pipe bending with these long-arm protractors.

Digital Protractors

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

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.

Combination Squares

High-Accuracy Combination Square Heads

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

High-Accuracy Combination Squares

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

High-Accuracy Combination Square Blades

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

Starrett High-Accuracy Combination Square Heads

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

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 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.

Combination Squares

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

Scratch-Resistant High-Accuracy Combination Squares

A titanium coating protects the blade against scratches and wear.

Angle Squares

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

Squares

Squares with Graduations on Both Blades

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

High-Accuracy Square Sets

Ensure reliable, repeatable 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.

High-Accuracy Squares

Ensure reliable, repeatable angles.

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.

Squares with Adjustable Blade

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

Pipefitters' Squares

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

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.

Layout Marking and Drafting Tools

Triangle Straightedges/Protractors

A protractor and triangle in one, use these tools to quickly set any angle from 0° to 90°.

Folding Triangle Straightedges

Unfold and lock the corners to form a triangle for marking angles.

T-Squares

Draw and cut straight lines in drafting, graphics, and construction applications.

Combination Angle Indicator/Center-Locating
Punches for Curved Surfaces

Find the center of square and round materials, such as structural framing and pipe, and determine setup angles on milling machines and grinders.

Angle Transfers

Duplicate or transfer any angle.

Multi-Angle Transfers

Transfer multiple angles, draw parallel lines, or create a template to make repeated patterns and measurements.

Leveling and Aligning

Magnetic Digital Levels

These levels have a plastic housing.

Heavy Duty Digital Levels

These levels have a sturdy aluminum housing.

Proximity-Sensor Shaft Alignment Kits

Align rotary shafts with the help of a mobile app.
