For all the carpentry DIYers out there, the General Tools Angle Protractor Stainless Steel Square Head will guide you through finding your angle points for any home, school, or work project. First, you’ll want to loosen the nut in the center of the protractor arm. Place the square head on one leg of the angle while the protractor’s nut should be at the angle point. Next, you will rest the arm on the other leg of the spot you’re measuring. Then, tighten the nut in the center of the arm and read the angle measurement on the ruler’s head. When it comes to angled cuts, it’s wise to follow the old saying, “measure twice, cut once.” This level tool can help you measure angles precisely. At General Tools, we offer over 1,000 products to choose from. We’re proud to provide merchants, artisans, and DIYers worldwide with a broad range of affordable, specific-purpose mechanical hand tools and precision measuring and inspection gear.
PROTRACTOR ARM: It’s constructed of durable stainless steel and features a 6″ adjustable arm for setting the bevel, transferring angles, and finding your measurement. It’s an essential tool and gift idea for a fellow carpenter, student, or machinist.
CONSTRUCTION PROTRACTORS: This square head protractor has a 0 to 180-degree semi-circle scale in forward and reverses directions to measure all angles on the job. The 3-3/8″ x 2″ head helps anchor the protractor against objects to hold it in place.
ANGLE FINDER: Quickly and easily identify your angles with our rust-resistant measuring compass. The metal arm locks into place with a knurled thumb nut, allowing you to gauge the measurement of the inclination accurately.
MEASUREMENT TOOLS: The project possibilities are endless when using our high-quality square-head protractor tool. You can master the art of building new cabinets, tables, chairs, wooden desks, framing, and various furniture makings.
GENERAL TOOLS: We’re a recognized leader in designing and developing specialized precision tools dedicated to delivering exceptional customer service. We encourage artisans and DIYers to work smarter, measure better, and repair more productively.
Customers find the protractor works well for their needs, is made of heavy steel, and is inexpensive for checking angles. The accuracy receives mixed feedback, with some finding it extremely accurate while others note it’s off by about a degree. Durability is also mixed, with some saying it should last a lifetime while others report it coming apart quickly. The locking mechanism is problematic as the screw doesn’t tighten enough and the arm doesn’t stay locked in place, while readability is generally positive but one customer mentions needing a magnifying glass to read it.
