What Are Flat Shims?
Flat Shims are thin, flat pieces of material used to fill gaps between two surfaces. They correct misalignments, ensure even loading, and provide accurate spacing in machinery and structures.
Common Features:
- Shapes: Round, rectangular, or square.
- Materials: Metal, plastic, rubber, paper.
- Thickness Range: From fractions of a millimetre to several millimetres.

Ensure machinery, structural elements, or assemblies are perfectly positioned to spec.
2. Time-Saving Adjustments
Flat shims are quick to insert or remove, ideal for temporary or trial setups.
3. Cost-Effective Fitment
Avoid costly rework, machining, or custom part replacements.
4. Versatility
Use across sectors and applications – from HVAC to heavy manufacturing.
5. Safer, Smoother Performance
Reduced vibration and wear improve long-term reliability.
6. Reversibility
Easily remove or replace shims during maintenance or adjustments.

Solving Common Challenges with Flat Shims
Handling Errors?
Our shims are precision-cut and clearly marked for quick installation.
Material Deformation?
Choose from reinforced materials like stainless steel or laminated stock.
Corrosion Issues?
Use our 316 stainless or plastic options for harsh environments.
Need Flexibility?
We offer shim kits and peelable shims for real-time adjustment on site.
Tight Lead Times?
Standard shims ship fast, and custom orders are delivered within days.
Use Case: CNC Fixture Calibration
A customer needed to align their CNC fixture to within 0.01mm tolerance. We supplied laminated stainless-steel shims with marked thicknesses. This reduced their setup time by 70% and improved cutting accuracy.
