These precision 1-2-3 blocks, matched in pairs, maintain exceptional 0.0002-inch tolerance specifications, providing reliable reference standards for inspection. workholding and alignment procedures across diverse manufacturing applications. The 23 hole precision setup blocks configuration includes threaded mounting points that accept standard fixturing screws, enabling secure attachment of clamps, stops, and specialized tooling during machining operations. Understanding 123 blocks' uses begins with recognizing their fundamental role as precision height references and workholding foundations in machine tool setup procedures. For those learning how to use 1-2-3 blocks, the drilled pattern facilitates clamping workpieces at precise elevations while maintaining perpendicularity to machine table surfaces. Each matched pair of 1-2-3 blocks set undergoes rigorous grinding processes to achieve parallel and perpendicular surface relationships essential for accurate setup work. The hardened steel construction resists deformation under clamping loads, ensuring these workholding precision blocks maintain dimensional integrity throughout continuous production use. Machinists appreciate the versatility of having multiple mounting options within compact 1X2X3 inch dimensions. The threaded holes accept 1/4-20 and M6 hardware commonly found in machinist setup jig tool inventories. These 1-2-3 blocks serve applications ranging from simple part elevation to complex multi-piece fixture assemblies requiring precise spatial relationships. The 0.0002-inch tolerance represents a practical balance between ultra-precision and cost-effectiveness for production environments. Precision-ground surfaces provide reliable datums for dial indicator measurements and tramming procedures. The 23 hole precision setup block pattern includes holes on multiple faces, maximizing mounting flexibility for creative fixturing solutions.
