Description These shims have countless uses around the shop and also in combination with our squares. Each shim is ground on 6 sides with two magnets on the bottom face, there are 7 different heights and 4 pieces of each height in a set. The magnet sizes are carefully chosen so that the taller shims have enough magnetic force to hold them up sideways on a project while carrying some of the smaller shims. The thinner shims have smaller magnets which reduce the amount of force required to remove them. The shims are ground on all 6 sides to an accuracy of /-0.0009 which is less than 1/1024 of an inch! Think of a 1/32” reading on a machinist rule, now divide it by 32 again to get 1/1024 of an inch. Shims are hardened to HRC 50. Just remember, to properly measure these you need to use a micrometer mounted on a stand and with the shim wiped clean. A pair of calipers in the hand with a dirty shim will not get an accurate measurement.
