[Precision Scale] The marking gauge has a clear scale with a measuring range of 0-20 cm and an accuracy of up to 0.1 mm for precise readings, making it ideal for high-precision scribing and marking work. [High-Quality Material] The marking gauge is made of high-quality carbon steel, which is wear-resistant, corrosion-resistant and has high hardness. The surface is chrome-plated, rust-resistant and easy to clean, protecting the surface from corrosion and damage. [Hardened Edges] Since the edges of the scribing gauge are hardened, it is possible to avoid sharp corners and edges. This also achieves high dimensional stability and high accuracy of the metal. [Easy to Use] In the measuring position, the locking knob fixes the template so that it does not slip, marking measurements accurately, avoiding errors and improving work efficiency.
