Shop Shims - New and Expanded 40 pc Edition.
Adding to the original 28 piece Magnetic Shop Shims we now include a 12 pc non-magnetic thin shim set. They are non-magnetic because they are too thin to install magnets on them.
The new expanded set now includes non-magnetic shims in sizes of 1/32, 1/16,and 1/8.
Magnetic Shims - 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. These shims have countless uses around the shop and also in combination with our squares.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.
Thin Non-Magnetic Shims
Each shim is processed on top and bottom sides only. The sides are not ground on these and slightly undersized from their nominal (2x1”) dimensions. The shims are not hardened, but have a black oxide treatment. These shims are accurate in height to within 0.005” variance (+0.0035” / -0.0015)
