Magnetic Setup Block and Setup Shim Sets
Support metal workpieces at precise angles or create accurate spacing with the blocks and shims in these sets. The blocks have neodymium magnets—powerful rare earth magnets—embedded in one face for a strong hold on shims or other metal surfaces. Their surface is hardened for durability and wear resistance. The shims are not hardened, but they have a black-oxide coating that helps prevent corrosion and wear. Blocks are ground parallel and square on all six sides, and the shims are ground on both faces.
Magnets may lose their holding power at temperatures above 175° F, so avoid extended heat exposure.

Setup Shims
Fine-tune height, spacing, and alignment when working with setup blocks. Made to match standard setup block dimensions, these shims are ground parallel and square to tight tolerances. Use them to level workpieces during machining and inspections. A black-oxide finish helps protect them from corrosion and wear.
Granite Setup Blocks
Machined in pairs, these blocks are precision ground to tolerances thinner than a sheet of paper to give you the flattest and squarest surface for positioning workpieces. Since they are perfectly aligned to one another, they’ll keep your workpieces level and parallel. Also known as 1-2-3 blocks, they're typically used to elevate, support, and align parts for measuring and inspecting. They're made from granite, so they won’t scratch the surface of your workpiece. They also won’t warp when temperatures fluctuate. Unlike metal blocks, these granite blocks are nonmagnetic, so they won’t interfere with sensitive electronic equipment. They come with a certificate of accuracy that's traceable to NIST.
Inspection-grade A blocks are your go-to for general inspections and quality-control work. These blocks are slightly less precise than grade AA blocks with double the tolerance.
Laboratory-grade AA blocks are best for precision inspections and quality-control work in calibration labs. These blocks have the tightest tolerance for the highest level of accuracy.
