Shim Washers Stainless Steel 4x6 Precision Spacer Kit for Bearings Gearboxes CNC and RC Tuning Assortment 40 Pieces 10 Units x 0.1/0.2/0.3/0.5 mm Deburred Flat Tight Tolerance Professional Use

Dial in perfect spacing with this metric shim washers assortment, engineered for repeatable results in precision builds. The set contains 40 pieces in A2 stainless steel, size 4x6, with 10 units each of 0.1, 0.2, 0.3 and 0.5 mm. Every shim washer is deburred and flat to protect components, maintain tight tolerance, and ensure smooth assembly without scratching delicate seats or shafts.Professional performance: eliminate play in bearings, set preload, center gears, and refine gear mesh with consistent accuracy. These stainless steel washers resist corrosion and deformation, staying stable under load and temperature changes. Use single shims for micro adjustments or stack them to reach the exact spacer thickness you need—no rework, no guesswork, and no extra machining steps on critical parts.Productivity built in: each thickness arrives individually packed and labeled for instant identification in your toolbox or on the bench. A sealed outer bag keeps the complete assortment clean, protected, and ready for field service. Spend less time searching and more time fixing—ideal for maintenance teams, makers, and technicians who demand speed, clarity, and reliable organization on urgent jobs.Broad versatility: perfect for bearings, bushings, gearboxes, CNC fixtures, drones, and RC tuning. The flat profile delivers uniform contact and predictable load distribution, helping you control tolerances, reduce vibration, and improve efficiency. Achieve quiet, smooth mechanisms on the first attempt while preserving perpendicularity and alignment across assemblies, jigs, and test rigs.What’s included: 40 A2 stainless shim washers 4x6 across 0.1 0.2 0.3 0.5 mm (10 per thickness), with clean edges and natural finish. Add this precisely curated kit to your bench and unlock faster builds, simpler alignment, and high confidence in every mechanical adjustment you make—whether in the shop, the lab, or the field.
