Precision Brand 81430 Slotted Shim Stock 0.4mm 4in 10pc

Product Description

The PRECISION BRAND 81430 is a slotted stainless steel shim stock sheet used for precise mechanical alignment, leveling, and gap adjustment in industrial and trade applications. Each piece measures 0.4 mm thick, 4 inches long, and 100 mm wide, with a 1-1/4 inch wide slot that allows the shim to slide into position around fasteners or shafts without full disassembly. The stainless steel construction resists corrosion and holds up in wet, chemical, or high-temperature environments. This package contains 10 pieces. Machinists, millwrights, pipefitters, and maintenance technicians are the primary installers for this type of shim stock.

Slotted shim stock in this thickness range is commonly used in equipment alignment tasks such as motor and pump base leveling, flange shimming, and bearing housing adjustment. The 0.4 mm thickness fits applications requiring fine incremental adjustment. The slot design speeds up installation by eliminating the need to fully remove bolts or studs. This product is suitable for both light industrial and heavy mechanical service environments where dimensional precision is critical.

Key Features

• 0.4 mm thickness for fine-increment gap and alignment adjustment
• Slotted design with 1-1/4 inch wide slot allows installation around bolts without full disassembly
• Stainless steel material resists corrosion in wet and chemical environments
• 100 mm wide by 4 inch long sheet provides adequate coverage for most base and flange applications
• Comes in a 10-piece package for multi-point alignment jobs

Compatibility

Designed as a general-purpose slotted shim stock for use in mechanical alignment applications involving bolted assemblies, motor bases, pump flanges, and similar equipment where 0.4 mm incremental adjustment is required.

Installation Notes

Installation is typically performed by millwrights, machinists, or maintenance technicians. De-energize and lock out all equipment before shimming any rotating machinery or powered assemblies. Slide the shim into position using the slot to work around fasteners without full disassembly, and verify alignment with a dial indicator or feeler gauge after placement. Do not use shims to compensate for structural damage or out-of-spec mounting surfaces.
