Setup Blocks
Create setups with precise angles and accurate spacing for measuring, inspection, or machining. These blocks are precision ground to tight tolerances on all six faces, making them flat, square, and parallel. Made of hardened steel, they resist wear, so they’ll stay precise even with heavy use.

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.
Setup Blocks for Welding
Designed to fit your welding fixturing system, these blocks make great mounting bases, supports, or positioning stops. The holes are spaced to fit with locating pins, clamps, and other accessories, so they’re ideal for repeatable setups. They don't have tight tolerances, so choose a different block for precision machining or inspecting. A black-oxide finish protects them from corrosion and wear.

Magnetic Setup Blocks
Align workpieces with accurate spacing or support them at precise angles. These blocks anchor to your setup with neodymium magnets without clamps getting in your way. Made of hardened steel, they’re durable and wear resistant. All six sides are ground parallel and square.
Magnets may lose their holding power at temperatures above 185° F, so avoid extended heat exposure.

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.
