These 301 stainless steel shim plates are built for hobbyists, machinists, and hands-on builders who need exact, repeatable spacing without cutting down thicker stock.\u003c\/p\u003e\n\u003cp\u003eEach sheet is made from 301-grade stainless steel — a chromium-nickel alloy known for its spring-like resilience and moderate corrosion resistance. Sheets are available in thicknesses from 0.01 mm (≈ 0.0004 in) up to 1 mm (≈ 0.039 in), in two footprints: 100 × 100 mm (≈ 3.94 × 3.94 in) and 100 × 300 mm (≈ 3.94 × 11.81 in). Surface finish is a standard mill\/2B finish unless otherwise noted in the variant.\u003c\/p\u003e\n\u003cp\u003eTypical applications include leveling CNC router beds and lathe tool posts, shimming door hinges and cabinet hardware, filling tolerance gaps in custom metal fabrication, and creating thin spring-steel flexures for DIY robotics and automation projects.
