Precision stainless-steel shims for machinery

These 0.020 in. thick stainless-steel shims come in a pack of 20 and are designed for spacing and alignment tasks. Each piece measures 4 in. by 4 in. with a 1 1/4 in. wide by 2 3/4 in. deep slot and a 3/4 in. by 2 1/4 in. tab for handling. The 18-8 alloy and full-hard temper resist corrosion and hold flat under load.

Replaces makeshift shim stock when repeatable

The +/- 0.001 in. thickness tolerance eliminates the guesswork of folded metal or paper shims. Switching is worth it when equipment alignment drifts because improvised shims compress unevenly or corrode. The C-4 trade size fits existing bolt patterns so no re-drilling is required.

Fits standard C-4 bolt slots

The slotted, tabbed design slides onto anchor bolts or studs without disassembly of the joint. Stainless construction means the shims stay in place permanently without rust staining concrete or steel. The 20-piece pack keeps a maintenance kit stocked for multiple alignment jobs across a plant.

Questions about this item

What bolt or stud diameter does the 1 1/4 in slot width and 2 3/4 in slot depth accommodate?

The 1 1/4 in slot width and 2 3/4 in slot depth fit standard anchor bolts and studs up to roughly 1 in diameter, allowing the shim to slide over them without disassembly.

Do I need to remove the anchor bolt or can the tabbed design slide around it?

The tabbed, slotted design lets you slide the shim around an installed bolt; just lift the tab, position the slot over the stud, and lower the shim into place.

Will the 0.020 in thickness and +/-0.001 in tolerance hold up under heavy equipment vibration?

The 18-8 stainless steel, full-hard temper and tight +/-0.001 in thickness tolerance resist compression set and corrosion, so the shim maintains its 0.020 in thickness under sustained vibration.
