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.
