Precision Brand 42330 Stainless Steel Slotted Shim 20-pack

Product Description

The PRECISION BRAND 42330 is a stainless steel slotted shim used to correct alignment and leveling issues on motors, pumps, generators, and other industrial or plant machinery. Each shim measures 3 inches by 3 inches with a thickness of 0.010 inches, providing a precise, consistent spacer for tight tolerance applications. The slotted design allows the shim to be inserted or removed without fully disassembling the equipment, saving time during setup and adjustment. This pack contains 20 shims and is suitable for use by millwrights, maintenance technicians, HVAC mechanics, and other trade professionals who require repeatable shim stock on the job.

These shims are well suited for use in mechanical alignment tasks across residential and commercial settings. Common applications include leveling pump bases, shimming motor feet to align drive shafts, and correcting equipment height on compressors, fans, and similar rotating machinery. The stainless steel construction makes them appropriate for environments with moderate moisture or chemical exposure where carbon steel shim stock would be prone to corrosion.

Key Features

• Stainless steel construction resists corrosion in wet or chemically active environments
• Slotted design allows installation and removal without full disassembly
• Consistent 0.010-inch thickness for repeatable, precision spacer applications
• 3 x 3 inch footprint fits standard motor base and pump foot configurations
• Pack of 20 shims provides job-site quantity for multiple adjustments

Compatibility

Designed for use as alignment and leveling shim stock for motors, pumps, generators, and general plant machinery requiring a 3 x 3 inch slotted shim at 0.010-inch thickness.

Installation Notes

De-energize and lock out all equipment before inserting or adjusting shims under motor feet or machinery bases. The slotted opening allows the shim to slide into position over anchor bolts without removing fasteners completely. Use a calibrated dial indicator or laser alignment tool to verify shaft alignment after shimming. Follow applicable machinery installation standards and any equipment manufacturer torque requirements when re-securing fasteners.
