Maudlin Products MSB012-20 Slotted Shim Stock 20-pack

Product Description

The MAUDLIN PRODUCTS MSB012-20 is a slotted shim stock pack designed for precision shimming, alignment, and leveling tasks across industrial and mechanical service applications. Each shim measures 0.012 inches thick, 3 inches long, and 3 inches wide, with a 7/8-inch wide slot that allows the piece to slide into position around a fastener or shaft without full disassembly. Fabricated from 302/304 stainless steel, these shims offer corrosion resistance and dimensional stability under load. The pack contains 20 pieces, making it practical for jobs requiring multiple shims or iterative fit adjustments. HVAC technicians, millwrights, plumbers, and equipment installers use this type of shim stock for alignment and leveling work.

Slotted shim stock in this thickness range is commonly used when aligning equipment bases, leveling mechanical components, or correcting minor dimensional gaps during installation or service. The 0.012-inch thickness is a standard increment well suited to fine-tolerance alignment work. The stainless steel construction makes these shims appropriate for environments where mild corrosion exposure, moisture, or temperature cycling is expected. This pack is applicable across residential and light commercial mechanical installations wherever a slotted, thin-gauge stainless shim is required.

Key Features

• 0.012-inch thickness for fine-tolerance alignment and leveling
• 7/8-inch wide slot allows installation without full fastener removal
• 302/304 stainless steel construction provides corrosion resistance
• 3 inch x 3 inch footprint suits a wide range of equipment bases and flanges
• 20-piece pack supports multi-point leveling or iterative fit work

Compatibility

Designed as a general-purpose slotted shim stock suitable for mechanical alignment, equipment leveling, and gap adjustment applications where a 0.012-inch thick, 3 inch x 3 inch stainless steel shim is specified.

Installation Notes

Shim stock installation is typically performed by millwrights, HVAC technicians, or plumbers during equipment alignment and leveling procedures. Always de-energize or shut down equipment before inserting or adjusting shims under load-bearing surfaces. Use appropriate personal protective equipment when cutting or trimming shim material, as stainless steel edges can be sharp. Verify final alignment with appropriate measuring tools after shimming is complete.
