What are Stainless Steel Shims?

A stainless steel shim is a thin, precisely manufactured piece of metal used to fill gaps, adjust alignment, level components, and absorb mechanical stress between two mating surfaces. Unlike ordinary packing materials, SS shims maintain their dimensional integrity under heat, pressure, vibration, and corrosive environments — making them indispensable in precision engineering. Aashish Metals supplies the following types under our broader shims product range:

Shim Type	Description	Common Use
Flat / Plain Shims	Solid rectangular or square sheets cut to size	General levelling, machine alignment
Slotted / Horseshoe Shims	U-slot cut for easy installation without full disassembly	Shaft alignment, bearing housings
Precut Shims	Pre-stamped to standard dimensions	Fast assembly, OEM applications
Shim Stock Rolls / Strips	Continuous coils in various thicknesses	Workshop use, custom cutting on-site
Shim Washers	Round disc shims with centre hole	Bolt/flange gaps, pump bearing adjustment
Custom / Punched Shims	Any shape, hole pattern or profile per drawing	Aerospace, defence, precision instruments

We also supply related products including brass shims, copper shims, and bimetal strips for applications requiring different material combinations.

Stainless Steel Shims: Frequently Asked Questions

What are stainless steel shims used for?

Stainless steel shims are used to fill small gaps between two mating surfaces, achieve precise alignment, level machinery and equipment, absorb vibration, compensate for manufacturing tolerances, and adjust clearances in assemblies. They are widely used in pump alignment, turbine rotor shimming, flange face mating, machine base levelling, automotive engine shimming, and structural steel erection. Their corrosion resistance makes them particularly valuable in outdoor, marine, chemical, and food-processing environments where mild steel shims would rust and contaminate.

What is the price of a stainless steel shim?

The stainless steel shims price in India depends on several factors: grade (SS 304 is the most economical; SS 316L and 904L are priced higher), thickness (thinner gauges like 0.05 mm cost more per kg due to higher rolling precision), dimensions, surface finish, quantity, and certification requirements. As a guide, standard SS 304 shims in common sizes typically range from ₹ 350 to ₹ 900 per kg depending on thickness and finish. SS 316/316L shims are approximately 20–30% higher. For an accurate, competitive quote on your specific requirement — including custom sizes and bulk orders — contact Aashish Metals directly.

What is the purpose of shims?

The primary purpose of a shim is precision gap adjustment. In engineering, no two machined surfaces are ever perfectly flat or perfectly spaced — shims bridge that gap without permanent modification to the components. This allows assemblies to be built to exact tolerances, enables easy disassembly and reassembly, facilitates field adjustments during maintenance, and extends equipment life by ensuring loads are distributed evenly across mating faces. In construction, shims level structural members. In instrumentation, they set precise sensor distances. In automotive manufacturing, they control valve clearances.

What thickness of stainless steel shim should I use?

The right thickness depends on the gap to be filled and the required precision. Ultra-thin shims (0.05 mm – 0.10 mm) are used where tolerances are critical — optical, instrumentation, or precision bearing applications. Standard shims (0.25 mm – 1.00 mm) cover most pump, compressor, and machine alignment work. Thicker shims (1.5 mm – 3 mm) are used for structural levelling. For complex stacks, engineers combine multiple thin shims rather than one thick piece to achieve the exact clearance required.
