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
-
