Shim Sheets
Shim Sheets are ultra thin metal sheets used primarily for precision alignment, spacing, and leveling in industrial and engineering applications. They are manufactured in highly accurate thicknesses, typically ranging from 0.02 mm to 3 mm, to meet exact dimensional tolerances.
Shim sheets are essential in machine tool setups, automotive components, aerospace systems, and precision instruments, where even the smallest misalignment can cause performance issues.
Moksh Tubes & Fittings LLP supplies premium quality shim sheets in a wide range of materials, thicknesses, and surface finishes, conforming to ASTM, ASME, DIN, EN, and JIS standards.
