Precision Brand 81440 Slotted Shim Stock 10 Piece

Product Description

The PRECISION BRAND 81440 is a slotted stainless steel shim stock used to fill gaps, set clearances, and align components in mechanical assemblies. Each piece measures 0.7 mm thick, 4 inches long, and 100 mm wide, with a 1-1/4 inch wide slot for easy installation around fasteners and shafts without full disassembly. The stainless steel construction resists corrosion and holds up in wet or chemically active environments. This package includes 10 pieces. Machinists, millwrights, and maintenance technicians use shim stock like this for precision alignment work in industrial, HVAC, and mechanical service applications.

Slotted shim stock is a standard solution for leveling equipment bases, aligning motor and pump shafts, and setting bearing clearances. The slot design allows the shim to slide into position laterally without removing the fastener entirely, which speeds up service on installed equipment. This product suits residential and light commercial mechanical work as well as industrial maintenance settings where stainless steel material is specified for corrosion resistance or sanitary requirements.

Key Features

• Stainless steel construction resists corrosion in wet and chemically active environments
• 1-1/4 inch wide slot allows installation around fasteners without full disassembly
• 0.7 mm thickness for precise gap and clearance control in mechanical assemblies
• 100 mm width provides a broad bearing surface for stable shimming
• Package of 10 pieces supports multiple simultaneous shimming points

Compatibility

Designed as a general-purpose slotted shim stock suitable for mechanical alignment, leveling, and clearance-setting applications where stainless steel material and a 1-1/4 inch slot width are required.

Installation Notes

Slotted shim stock is typically installed by millwrights, maintenance technicians, or mechanical contractors. De-energize and lock out all power to rotating or pressurized equipment before inserting or removing shims. Use the slot to slide the shim laterally into position around the fastener rather than forcing it under load, which can deform the material and compromise alignment accuracy. Do not stack more shim pieces than necessary to achieve target clearance, as excessive stacking reduces joint stability.
