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 Parallels
Support and align workpieces for precise measuring and inspecting. Made of black granite, these parallels won’t rust or warp from temperature changes, and they won’t scratch surfaces. Unlike metal parallels, they’re also nonmagnetic, so they won’t interfere with sensitive electronic equipment. Made in pairs, these parallels are precision ground to tight tolerances for matching flat surfaces on two or four sides. They come with a certificate traceable to NIST confirming their accuracy.
Inspection Grade A parallels are used for general inspections and quality-control work. They’re slightly less precise than Grade AA ones. Laboratory Grade AA parallels have the tightest tolerance for the highest level of accuracy. They’re best for inspections and quality-control work in calibration labs.
Parallels with 2 precision-ground sides have a tight parallel tolerance on the top and bottom edges. Parallels with 4 precision-ground sides have a tight parallel tolerance on the top edge, bottom edge, and both faces.
