Precision Brand 81425 Slotted Shim Stock 10 Piece

Product Description

The PRECISION BRAND 81425 is a slotted stainless steel shim stock sheet used to fill gaps, set clearances, and align machinery or structural components during installation and maintenance work. Each piece measures 0.25 mm thick, 4 inches long, and 100 mm wide, with a 1.25-inch wide slot for positioning around fasteners or shafts without full disassembly. The stainless steel construction resists corrosion in wet or chemically exposed environments. This package contains 10 pieces. Machinists, millwrights, pipefitters, and general maintenance technicians typically use this product when precise tolerance adjustment is required.

Slotted shim stock is suited for residential and commercial mechanical applications including pump and motor alignment, pipe hanger leveling, equipment base shimming, and flange gap adjustment. The slot allows the shim to slide into position around a bolt or stud while the equipment remains partially assembled, reducing disassembly time. The 0.25 mm thickness makes this a fine-tolerance shim appropriate for applications requiring incremental stack adjustment. The 10-piece pack supports repeat jobs or staged builds where multiple shimming points are involved.

Key Features

• Slotted design allows installation around fasteners without full disassembly
• 0.25 mm thickness for fine-tolerance gap adjustment and alignment work
• Stainless steel material provides corrosion resistance in demanding environments
• 1.25-inch wide slot accommodates a range of fastener and shaft diameters
• 10-piece pack supports multi-point shimming applications
• 4-inch length and 100 mm width offer a practical working surface for most standard alignment tasks

Compatibility

Designed as a general-purpose slotted shim stock for mechanical alignment, gap setting, and leveling applications across industrial, commercial, and trade service work.

Installation Notes

De-energize and lock out equipment before inserting or adjusting shims near rotating components. Stack multiple shims as needed to achieve target clearance, verifying with feeler gauges or dial indicators as appropriate for the application. Wear cut-resistant gloves when handling shim stock edges, as thin metal sheet edges can be sharp. Follow applicable equipment manufacturer tolerances and any relevant ASME or facility maintenance standards when setting final alignment values.
