Precision Brand 42405 Stainless Steel Slotted Shim 20-pack

Product Description

The PRECISION BRAND 42405 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 4 inches by 4 inches with a thickness of 0.001 inches, allowing for precise incremental adjustments in tight-tolerance applications. The slotted design enables installation and removal without fully disassembling the equipment. This pack contains 20 shims, giving technicians enough material to complete multi-point alignment jobs or keep spares on hand for ongoing maintenance work. Stainless steel construction resists corrosion and holds up in demanding service environments.

These shims are suited for use in industrial maintenance, millwright work, and mechanical service applications where precise equipment alignment is required. Common use cases include shimming electric motor bases, pump flanges, compressor feet, and generator mounts. The 0.001-inch thickness makes them appropriate for fine-tuning alignment tolerances. Technicians working in HVAC mechanical rooms, pump stations, or manufacturing facilities will find these useful for both initial installation and ongoing predictive maintenance tasks.

Key Features

• Stainless steel construction provides corrosion resistance in wet or harsh environments
• Slotted design allows shim placement without full equipment teardown
• 4 x 4 inch footprint fits standard motor and pump base applications
• 0.001 inch thickness enables fine, incremental alignment correction
• Pack of 20 provides sufficient quantity for multi-point or multi-machine jobs

Compatibility

Designed for use with motors, pumps, generators, and general plant machinery requiring precision alignment and leveling adjustments.

Installation Notes

Installation is typically performed by millwrights, mechanical contractors, or licensed HVAC and plumbing technicians during equipment commissioning or realignment service. De-energize and lock out equipment before shimming motor or pump bases. Use a dial indicator or laser alignment tool to verify correction after shim placement. Follow equipment manufacturer torque specifications when retorquing anchor bolts after adjustment.
