Precision Ground Grade A Granite Surface Plate for Accuracy

The HHIP 4401-3020 Granite Surface Plate is an essential tool for any workshop or manufacturing environment. Measuring at 11.81 in x 7.87 in x 2.36 in, this plate is designed to provide a high degree of flatness, ensuring that your measurements are accurate to within +/- 0.0001 in. This level of precision is crucial for professionals who rely on exact measurements for their projects.

Constructed from Grade A granite, this surface plate meets or exceeds Federal Specifications GGG-P-463C, making it a reliable choice for those who demand quality. The Grade A surface plate is not only durable but also non-magnetic and non-conductive, which adds to its versatility in various applications.

Granite surface plates are widely used for measuring the flatness and squareness of other objects. They are ideal for laying out parts, calibrating instruments, and setting up tools. With the HHIP granite plate, you can easily check parallelism and perpendicularity, ensuring that your work is precise and accurate.

One of the standout features of this plate is its ability to serve as a work surface for assembling, inspecting, and marking parts. The hardness of granite makes it tougher than steel, meaning it won't nick or burr easily, providing a long-lasting surface for your tasks. This durability is essential for maintaining the integrity of your measurements over time.

Additionally, the precision ground surface of this plate is checked by an auto collimator, ensuring overall accuracy assurance. This meticulous attention to detail guarantees that you are working with a product that has been rigorously tested for performance.

Whether you are a machinist, engineer, or hobbyist, the HHIP granite surface plate is a valuable addition to your toolkit. Its various sizes and levels of flatness and accuracy make it suitable for a wide range of applications, allowing you to choose the perfect plate for your specific needs.

In summary, the HHIP 4401-3020 Grade A Granite Surface Plate is a top-tier choice for anyone seeking precision and reliability in their measurements. With its robust construction, high accuracy, and versatile applications, this granite surface plate is sure to meet and exceed your expectations.
