ZXGLW is a smooth plug gauges manufacturer and supplier from China. We have independent research and development capabilities, and introduce imported equipment and materials, constantly explore and innovate, and pay great attention to product quality throughout the entire manufacturing process. This plug gauge is easy to carry and use, can perform accurate measurements, has high hardness and durability, and more importantly, has good accuracy.
• High-precision measuring head: Smooth plug gauges are made of high-performance GCR15 steel, which has undergone rigorous heat treatment and a hardness of 53-60 rhc. It has high brittleness, permeability, high hardness and excellent resistance to contact fatigue, ensuring the accuracy and stability of measurement. After fine grinding by high-precision imported special grinders, each measuring head is fully inspected by high-precision testing equipment.
• High-quality aluminum tube handle: Made of high-quality aluminum tube material, it is light in weight and easy to operate and carry. The surface is treated with electrophoresis technology, which is not only non-slip and wear-resistant, but also firmly connected, making you feel comfortable and durable during use.
• Overall advantages of the product: The plug gauge has high hardness, high precision and long life. From material selection to production process, every link is strictly controlled. Whether it is length, size or stability, it has excellent performance and is your right-hand man for accurate measurement.
Material: bearing steel (GCr15)
Size range: smooth plug gauges are available in a full range of sizes, suitable for different hole diameters, and can be customized, with the ability to accept non-standard parts.
