General Tools Angle Protractor #17 – Stainless Steel Square Head with 6-Inch Arm for Carpenters & Woodworking

Overview

The General Tools Angle Protractor #17 is a durable stainless steel square-head measuring tool designed for carpenters, woodworkers, and DIY enthusiasts. Its robust build and precise design help you plan bevels, set angles, and translate measurements from one workpiece to another with confidence.

The protractor features a 6-inch adjustable arm, a knurled thumb nut for secure locking, and a 0 to 180-degree semi-circle scale that can read in both forward and reverse directions. With a compact 3-3/8" x 2" head, it clamps neatly against edges and stays aligned during marking and transfer tasks. The rust-resistant metal stands up to routine shop use, so you can rely on repeatable readings across multiple projects.
