Precision Shim Washer Kit 448pcs 304 SS 0.1-0.5mm

Achieve exact spacing with this KunTensile 448-piece precision shim washer kit, featuring DIN 988-compliant stainless steel spacers in six sizes (3x6mm to 10x16mm) with thicknesses from 0.1mm to 0.5mm. Each shim (±0.01mm tolerance) is crafted from durable 304 stainless steel for superior corrosion resistance and strength, ideal for outdoor, high-humidity, or precision-engineered applications.

Perfect for eliminating end-play in bearings, fine-tuning motor preloads, correcting misalignments in CNC routers or 3D printer rails, and adjusting clearances in small engines, RC vehicles, or industrial machinery. The stackable design allows for incremental adjustments in 0.1mm increments, reducing NVH (noise, vibration, harshness) and wear. Includes 20 sizes with 20pcs each (except 10x16mm: 12pcs).
