Precision Brand 42320 Stainless Steel Slotted Shim 20 Pack

Product Description

The PRECISION BRAND 42320 is a stainless steel slotted shim supplied in a pack of 20 pieces, each measuring 3 x 3 x 0.004 inches. Slotted shims are used to make precise alignment and leveling corrections on rotating and stationary equipment without requiring full disassembly. The slot allows the shim to slide around a bolt or shaft rather than thread over it, reducing downtime during adjustment. The stainless steel construction resists corrosion and holds its geometry under load, making these shims a reliable choice for maintenance professionals working in demanding plant environments.

These shims are used in industrial and commercial maintenance applications where tight tolerances are required. Typical use cases include shimming motors, pumps, generators, compressors, and other base-mounted plant machinery. They are well suited for mechanical contractors, millwrights, and plant maintenance technicians who need consistent, dimensionally stable shim stock in a standard 3 x 3 inch footprint. The thin 0.004-inch gauge is suited for fine alignment work where small corrections are needed.

Key Features

• Slotted design allows installation around fasteners without full bolt removal
• Stainless steel construction provides corrosion resistance and dimensional stability under load
• 0.004-inch thickness enables precise fine-tolerance alignment corrections
• 3 x 3 inch square footprint fits a wide range of base-mounted equipment
• Pack of 20 provides quantity for multi-point shimming jobs or recurring maintenance needs

Compatibility

Designed for alignment and leveling of base-mounted equipment including motors, pumps, generators, and other plant machinery requiring precise shim correction.

Installation Notes

Slotted shims are typically installed by millwrights or mechanical maintenance technicians as part of precision alignment procedures. Always de-energize and lock out equipment before performing alignment work. Slide the shim over the mounting bolt into position at the base of the equipment, then re-torque fasteners per the equipment manufacturer specifications. Verify alignment with appropriate measurement tools after adjustment.
