High-Precision Flat Metal Washers – Custom Round Shims and Spacers
for Mechanical and Electrical Applications
Product Description:
These flat metal washers are precision-engineered components used for load distribution,
spacing, and tolerance control in mechanical assemblies. With a
uniform surface and accurate inner and outer diameters, these
washers reduce friction, prevent surface damage, and ensure stable
fastening.
Ideal for use in automotive, electronics, heavy machinery, and
aerospace industries, these discs can also serve as gap fillers, calibration shims, electrical insulators (when
coated), or thermal pads depending on the material used.
The high precision and customizable dimensions make them suitable
for both standard fastening systems and high-tolerance engineering assemblies.
Features:
✅ High dimensional accuracy for tight fits and tolerance compensation
✅ Multiple thickness options for fine-tuning mechanical clearances
✅ Corrosion-resistant materials such as stainless steel or brass
✅ Mirror-finish or matte options for different use environments
✅ Smooth edges for safe assembly in automated production lines
✅ Suitable for static or dynamic load applications
