- 1-2-3 blocks, also known as 123 blocks, are precision-ground metal blocks measuring exactly 1" x 2" x 3". Designed for accuracy and durability, they are essential tools for machining, metalworking, and inspection applications. Commonly used to align and square workpieces in vises, fixtures, and jigs, 1-2-3 blocks help ensure precise setups for milling, drilling, and assembly. Their tight tolerances support consistent, repeatable positioning in both manual and CNC machining operations. Featuring precision-drilled and tapped holes, these setup blocks allow secure clamping of small or irregular parts. They also function as spacers or parallels for exact height and spacing, and can be used on surface plates for quick inspection and flatness checks. Ideal for machine shops, manufacturing, and maintenance environments, 1-2-3 blocks provide reliable performance for a wide range of precision setup and fixturing tasks.
