Precision Brand 42425 Stainless Steel Slotted Shim 20 Pack

Product Description

The PRECISION BRAND 42425 is a stainless steel slotted shim designed for precision alignment and leveling of motors, pumps, generators, and other industrial plant machinery. Each shim measures 4 inches x 4 inches with a thickness of 0.005 inches, providing fine-increment adjustment capability where exact tolerances matter. The slotted design allows the shim to be inserted or removed without fully disassembling the mounting hardware, saving time during alignment procedures. This pack contains 20 individual shims, making it practical for shops and field techs who work alignment tasks regularly.

These shims are suited for use in commercial and industrial maintenance settings where machinery alignment is part of routine service. Common applications include base plate leveling, shaft alignment correction, and equipment shimming on motors, compressors, and pump skids. The stainless steel construction holds up in environments with moisture, mild chemicals, or temperature variation, making this pack a reliable stock item for maintenance crews and millwrights.

Key Features

• Slotted design allows installation and removal without fully loosening fasteners
• 0.005-inch thickness provides fine-increment alignment adjustment
• 4 inches x 4 inches footprint fits standard motor and pump base plates
• Stainless steel construction resists corrosion in wet or chemically active environments
• Pack of 20 shims for shop stock or recurring field use

Compatibility

Designed as a general-purpose slotted shim for alignment and leveling of motors, pumps, generators, and similar industrial machinery with standard base plate configurations.

Installation Notes

Installation is typically performed by millwrights, industrial maintenance technicians, or mechanical contractors during machinery alignment procedures. De-energize and lock out all equipment before inserting or adjusting shims beneath mounted machinery. The slotted opening allows the shim to slide into place around anchor bolts without full fastener removal, but bolts should be loosened sufficiently to relieve load before adjustment. Always verify final alignment with a dial indicator or laser alignment tool before returning equipment to service.
