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.

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.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003c!-- ⑥ CTA BAR --\u003e\n  \u003cdiv class=\"hdiy-cta\"\u003e\n    🛒 Select your material and thickness above, then add to cart — ships from our US warehouse.\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"304 Stainless Steel \/ 0.01×100×100mm \/ 1pcs","offer_id":52378557284626,"sku":"LFL05976x1","price":5.78,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.02×100×100mm \/ 1pcs","offer_id":52378557317394,"sku":"LFL05977x1","price":5.29,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.03×100×100mm \/ 1pcs","offer_id":52378557350162,"sku":"LFL05978x1","price":4.69,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.04×100×100mm \/ 1pcs","offer_id":52378557382930,"sku":"LFL05979x1","price":4.69,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.05×100×100mm \/ 1pcs","offer_id":52378557415698,"sku":"LFL05980x1","price":4.28,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.1×100×100mm \/ 1pcs","offer_id":52378557448466,"sku":"LFL05981x1","price":4.28,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.15×100×100mm \/ 1pcs","offer_id":52378557481234,"sku":"LFL05982x1","price":4.28,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.2×100×100mm \/ 1pcs","offer_id":52378557514002,"sku":"LFL05983x1","price":4.28,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.25×100×100mm \/ 1pcs","offer_id":52378557546770,"sku":"LFL05984x1","price":4.69,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.3×100×100mm \/ 1pcs","offer_id":52378557579538,"sku":"LFL05985x1","price":4.83,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.4×100×100mm \/ 1pcs","offer_id":52378557612306,"sku":"LFL05986x1","price":5.29,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.5×100×100mm \/ 1pcs","offer_id":52378557645074,"sku":"LFL05987x1","price":5.78,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.6×100×100mm \/ 1pcs","offer_id":52378557677842,"sku":"LFL05988x1","price":6.79,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.7×100×100mm \/ 1pcs","offer_id":52378557710610,"sku":"LFL05989x1","price":7.6,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.8×100×100mm \/ 1pcs","offer_id":52378557743378,"sku":"LFL05990x1","price":8.42,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.9×100×100mm \/ 1pcs","offer_id":52378557776146,"sku":"LFL05991x1","price":9.23,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 1×100×100mm \/ 1pcs","offer_id":52378557808914,"sku":"LFL05992x1","price":10.13,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 1.2×100×100mm \/ 1pcs","offer_id":52378557841682,"sku":"LFL05993x1","price":11.82,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 1.5×100×100mm \/ 1pcs","offer_id":52378557874450,"sku":"LFL05994x1","price":14.4,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 1.8×100×100mm \/ 1pcs","offer_id":52378557907218,"sku":"LFL05995x1","price":17.07,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 2×100×100mm \/ 1pcs","offer_id":52378557939986,"sku":"LFL05996x1","price":18.84,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 2.5×100×100mm \/ 1pcs","offer_id":52378557972754,"sku":"LFL05997x1","price":23.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture1of7_0f28c3c2-c59f-43e1-b948-78bbbdff0ff5.jpg?v=1781601206","url":"https:\/\/homediyer.com\/products\/304-stainless-steel-sheet-precision-shim-stock","provider":"HomeDIYer","version":"1.0","type":"link"}
