Timunr 1 Pair of Matched 1 x 2 x 3 Accuracy Parallel Blocks 11-Hole 0.0001 Squareness Alloy Steel 123 Blocks

• Material: Made of 40Cr steel, which is an alloy steel with good comprehensive mechanical properties and is currently one of the most widely used steels in the machinery manufacturing industry
• Dimensions and Accuracy: The three sides are 1, 2 and 3 respectively, the tolerance of size is about 0.0001, the squareness is 0.0001/1
• Holes: There are 11 holes in the block, 5 are threaded holes for clamping and the rest are unused holes. The 5 threaded holes are 5/16-18 in size, and the other holes are divided into large holes and small holes with diameters of 12.7mm and 8.7mm respectively
• Feature: Accuracy grade tool steel was quenched and ground on all six sides of the block
• Design: Through hole design, the two faces are not the same size
