Precision Hat Square: Manufactured according to DIN875 standard, our carpenter's square provides higher measuring accuracy than ordinary square rulers. The precise 90-degree angle can detect minimal vertical deviations, ensuring accurate measuring results. Exquisite Workmanship: The carpenter's square is made of solid carbon steel, carefully polished, heat-treated, and ground, making it stable, smooth, corrosion-resistant, and durable. The base of the combination square is connected by two embedded rivets to ensure stability, straightness, and parallelism. Unique Design: Our carpenter's square is designed with a clear laser-engraved scale, so it can also be used as a measuring tool. The milled groove in the inside corner helps clear burrs and debris. Versatile: This right angle carpenter's square is perfect for woodworking, setting up machines, building models, checking blade squareness, and more. A versatile engineering tool that meets many woodworking needs. Size: The combination square measures 7x10.5cm (including the base, base: 5mm). Compact enough to fit into many hard-to-reach places. Ideal gift for carpenters, engineers, machinists, or anyone who is passionate about woodworking or DIY.
