Precision Brand 81240 Slotted Shim Stock Stainless Steel 10 Pack

Product Description

The PRECISION BRAND 81240 is a slotted stainless steel shim stock used for precision alignment, leveling, and spacing in mechanical and industrial assemblies. Each piece measures 0.7 mm thick, 2 inches long, and 50 mm wide, with a 5/8-inch wide slot that allows the shim to slide into place around a fastener or shaft without full disassembly. Stainless steel construction provides corrosion resistance and dimensional stability under load. The package contains 10 pieces. Machinists, millwrights, and maintenance technicians use these shims when setting equipment clearances, aligning flanges, or correcting tolerances during assembly and installation work.

Slotted shim stock in this size range is commonly used in light industrial, commercial, and mechanical maintenance applications. The slot design speeds installation by allowing technicians to position the shim laterally over a bolt or stud rather than threading it axially. Typical use cases include machine base leveling, bearing housing alignment, pump and motor foot shimming, and general precision fit-up work where controlled spacing is required. Each shim in the 10-piece pack is consistent in thickness, making them suitable for stacking when additional clearance adjustment is needed.

Key Features

• Slotted design allows lateral installation over fasteners without full disassembly
• 0.7 mm thickness for fine clearance and alignment adjustment
• 50 mm wide profile provides stable surface contact during shimming
• 5/8-inch slot width accommodates common fastener sizes
• Stainless steel material resists corrosion in wet or humid environments
• 10 pieces per package for multiple adjustments or stacking applications

Compatibility

Designed as a general-purpose slotted shim stock suitable for mechanical alignment and spacing tasks in industrial, commercial, and maintenance settings where 0.7 mm stainless steel shims are required.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians as part of equipment alignment or assembly procedures. De-energize and lock out any equipment before placing or adjusting shims in rotating or pressurized systems. Use calibrated measuring tools to verify final clearances after shimming. Shims may be stacked to achieve intermediate thickness values, but verify combined stack height with a micrometer before finalizing the assembly.
