Gage Block Stack for 25.4 mm

Gage block stacks › 25.4 mm

This is the stack for a 25.4 mm gage block height, worked for the 88-piece metric set (and checked against the 112-piece set). For reference, 25.4 mm is exactly 1 in.

Step by step

Add the blocks from the finest increment to the thickest. After each block the "left to build" column shows what the remaining blocks must make up; it reaches 0 on the last block.

Other stacks for 25.4 mm (88-piece metric set)

• 20 + 3.5 + 1.4 + 0.5 (4 blocks)
• 20 + 3 + 1.4 + 1 (4 blocks)
• 20 + 3 + 1.39 + 1.01 (4 blocks)

More blocks means more wrung joints, so the shortest stack above is the one to prefer. These alternates help if a block in your set is missing or worn.

The same size in a 112-piece metric set

With the 112-piece metric set the fewest-block stack is 24 + 1.4 = 25.4 mm, 2 blocks, which is 1 fewer block than the 88-piece metric stack.

How to use this stack

1. Pull the 3 blocks listed from your 88-piece metric set and check the sizes marked on each one.
2. Wring the thickest blocks together first and add the thinner ones last. See how to wring gage blocks.
3. Let the stack and the part reach the same temperature before measuring (temperature correction).
