28-Piece Inch Gage Block Set: Block Sizes and Stack Examples
Gage block stacks › 28-piece inch set
The 28-piece inch set is a thin-block set made for building small heights and for adding fine steps to another set. It is built around the .02005 in half-tenth block and the .0201 to .0209 in series.
The block list below is the composition the free gage block calculator uses for this set. Sets from different makers can differ slightly, so check the sizes marked on the blocks in your own box.
All 28 blocks in the 28-piece inch set
| Series | Blocks | Sizes (in) |
|---|---|---|
| Half-tenth block | 1 | 0.02005 |
| 0.0001 in series | 9 | 0.0201, 0.0202, 0.0203, 0.0204, 0.0205, 0.0206, 0.0207, 0.0208, 0.0209 |
| 0.001 in series | 9 | 0.021, 0.022, 0.023, 0.024, 0.025, 0.026, 0.027, 0.028, 0.029 |
| 0.010 in series | 9 | 0.010, 0.020, 0.030, 0.040, 0.050, 0.060, 0.070, 0.080, 0.090 |
Total: 28 blocks, smallest 0.010 in, largest 0.090 in. All blocks laid end to end would measure 0.87955 in.
What sizes can it build?
Each block can be used once in a stack. Working it out for every size, every size in steps of 0.0001 in from 0.0400 to 0.8195 in can be built, as long as the stack uses each block only once.
Worked examples
Fewest-block stacks from the same solver the calculator uses; each one adds up to the target exactly.
| Target | Stack | Blocks |
|---|---|---|
| 0.0555 in | 0.025 + 0.0205 + 0.010 | 3 |
| 0.1234 in | 0.080 + 0.023 + 0.0204 | 3 |
| 0.2468 in | 0.090 + 0.080 + 0.030 + 0.026 + 0.0208 | 5 |
| 0.1500 in | 0.090 + 0.060 | 2 |
| 0.0875 in | 0.040 + 0.027 + 0.0205 | 3 |
If a block is missing or worn
Untick the block in the free gage block calculator and it finds the next-best stack from what is left. If your set includes wear blocks, they can be added to the ends of a stack to protect the working blocks; see gage block care and wear blocks.
