304 Stainless Steel Sheet Plate — Precision Shim Stock 0.01mm–2.5mm Thick | 100×100mm

Measure the gap or clearance you need to fill using a feeler gauge or digital caliper. Shim thicknesses in this listing range from 0.01mm (≈0.0004") for ultra-fine adjustments up to 2.5mm (≈0.098") for larger gaps. A common approach: order one size thinner than your measured gap and stack sheets as needed to dial in the exact clearance. For example, a 0.15mm gap could be filled with one 0.1mm sheet plus one 0.05mm sheet.

Generally, yes. 304 stainless steel offers good corrosion resistance in most outdoor, humid, and mildly corrosive environments thanks to its chromium oxide passive layer. For highly corrosive settings — such as saltwater marine environments or exposure to chlorides — 316 stainless steel is typically recommended. If you're unsure whether 304 suits your environment, contact us to confirm.

304 stainless steel typically has a tensile strength of around 515 MPa (≈75,000 psi) and a yield strength of approximately 205 MPa (≈30,000 psi) in the annealed condition. For thin foil gauges (under 0.1mm), the effective load capacity is limited by the sheet's cross-sectional area — these are best suited for gap-filling and alignment shimming rather than structural load transfer.

Yes. These are flat, unthreaded plates, so they work as shims or spacers with any standard metric (M2–M20) or imperial (#4 through 3/4") bolt or screw. You can drill custom holes to match your fastener pattern using standard HSS drill bits. No special threading or tapping is required.

Yes. Thinner sheets (generally under 0.3mm) can be cut with sharp metal shears, a utility knife against a steel straightedge, or a rotary tool. Thicker sheets (0.3mm and above) typically require tin snips, a metal-cutting blade, or an angle grinder for clean edges. Drilling is straightforward with HSS drill bits and cutting fluid. Deburr edges after cutting for safe handling.

Each order includes 1 piece (1pcs) at the thickness you select. To get multiple thicknesses, simply add each variant to your cart separately or increase the quantity for the same thickness. This makes it easy to build a custom stainless steel shim assortment for your toolbox or workshop.

In its annealed state, 304 stainless steel is generally considered non-magnetic (austenitic structure). However, cold-rolling during manufacturing can induce slight magnetism, particularly in thinner gauges. If magnetic neutrality is critical — for example, near Hall-effect sensors or MRI-adjacent equipment — please contact us to confirm the specific sheet's magnetic permeability before ordering.
