The Insize 8″ Inside Spring Caliper is designed for measuring internal dimensions with accuracy and consistency. Constructed from durable carbon steel, it features a smooth spring-adjustment mechanism that allows users to fine-tune measurements within a range of 0.87″ to 7.87″.
The rigid 8″ frame provides reliable performance when checking the inside diameters of holes, bores, pipes, and other internal features. Ideal for workshop, machining, and inspection applications where precision measurements are required.
