Precision Brand 42315 Stainless Steel Slotted Shim 20 Pack

Product Description

The PRECISION BRAND 42315 is a stainless steel slotted shim supplied in a pack of 20, designed for precision alignment and leveling of industrial equipment. Each shim measures 3 inches x 3 inches with a thickness of 0.003 inches, making it suitable for fine-tolerance adjustments where consistent material thickness is critical. The slotted design allows the shim to slide into position without full disassembly of the equipment being shimmed. Maintenance technicians, millwrights, and mechanical contractors install these shims on motors, pumps, generators, compressors, and other rotating or stationary plant machinery.

This shim is used in commercial and industrial plant maintenance settings where precise alignment is required to reduce vibration, extend bearing life, and maintain proper equipment geometry. The slotted opening makes installation faster in tight spaces where removing a shaft or fastener entirely is not practical. The 20-piece pack format suits service techs who need multiple shims on hand for a single job or want to stock a standard thickness for routine maintenance work.

Key Features

• Slotted design allows installation without full shaft or fastener removal
• Stainless steel construction resists corrosion in wet or chemically active environments
• 0.003-inch thickness suits fine-tolerance alignment applications
• 3 inches x 3 inches footprint fits a range of motor and pump base configurations
• Pack of 20 provides enough quantity for multi-point alignment jobs

Compatibility

Designed for use with motors, pumps, generators, and general plant machinery requiring precision alignment and leveling at the base or mounting surface.

Installation Notes

Millwrights and mechanical maintenance technicians typically install slotted shims during equipment alignment procedures. Power down and lock out the equipment fully before placing or adjusting shims under any motor or pump base. Use a dial indicator or laser alignment tool to verify final alignment after shimming. Do not stack more shims than necessary to achieve specification, as excessive stacking can reduce load stability at the mounting surface.
