Precision Brand 42520 Stainless Steel Slotted Shim 20-pack

Product Description

The PRECISION BRAND 42520 is a stainless steel slotted shim designed for precision alignment and leveling of industrial and mechanical equipment. Each shim measures 5 inches by 5 inches with a thickness of 0.004 inches, providing a thin, consistent layer for fine-tuning component positioning. The slotted design allows technicians to slide the shim into place without fully disassembling the equipment, saving labor time on the job. This pack includes 20 shims. Stainless steel construction resists corrosion and holds its shape under load, making it a reliable choice for maintenance environments where moisture or chemical exposure is a concern.

These shims are suited for use in industrial and commercial maintenance settings. Common applications include motor base alignment, pump leveling, generator mounting, and general plant machinery positioning. The 0.004-inch thickness is typically used where very fine adjustments are needed to bring equipment within specified tolerances. Maintenance technicians and millwrights working on rotating equipment installations will find this format practical for both initial setup and ongoing service calls.

Key Features

• Slotted design allows installation without full disassembly of the component
• 5 x 5 x 0.004 inch dimensions suit fine-tolerance alignment work
• Stainless steel material resists corrosion and deformation under load
• Pack of 20 shims supports multiple machines or repeat adjustments from a single purchase
• Consistent thickness across each shim ensures repeatable, accurate alignment results

Compatibility

Designed as an OEM-style replacement and general-use shim for motors, pumps, generators, and similar plant machinery requiring precise base alignment and leveling.

Installation Notes

Installation is typically performed by millwrights, industrial maintenance technicians, or licensed mechanics working on rotating equipment. Always de-energize and lock out the equipment before performing alignment or leveling work. Use a calibrated dial indicator or laser alignment tool to verify that target tolerances are achieved after shimming. Stack multiple shims as needed, but confirm total stack thickness with a micrometer before finalizing the installation.
