Measure the gap you need to fill with a feeler gauge or micrometer. For fine shimming and calibration work, thicknesses of 0.01–0.1mm are typically used. For structural spacers or gaskets, 0.2–1.5mm is generally more appropriate. When in doubt, order one step thinner than your measured gap — sheets can be stacked to reach the exact dimension needed.

This precision foil is generally manufactured from 304 stainless steel, which offers a good balance of corrosion resistance and formability. If your application requires higher corrosion resistance (e.g., marine or chemical environments), contact us to confirm the exact grade before ordering.

Stainless steel is inherently corrosion-resistant and performs well in most outdoor and humid environments. For prolonged exposure to saltwater or aggressive chemicals, 316-grade stainless is typically recommended. Contact us to confirm the material grade for your specific use case.

304 stainless steel shim stock typically has a tensile strength of approximately 515 MPa (75,000 psi) and a yield strength of around 205 MPa (30,000 psi). Actual values may vary slightly by thickness and temper. For load-bearing or safety-critical applications, please verify with your engineer.

Yes. Because this is flat shim stock (not a threaded component), it is compatible with any fastener system — metric or imperial. Simply cut or punch to the required shape to fit around M-series or SAE bolts as needed.

Yes. Thinner gauges (0.01–0.3mm) can generally be cut with sharp scissors or a craft knife. Thicker gauges (0.4–1.5mm) typically require metal shears, a rotary cutter, or a laser/waterjet for clean edges. Always deburr cut edges before handling to avoid injury.

Divide the mm value by 25.4. Quick reference examples:

• 0.01mm ÷ 25.4 ≈ 0.0004" (0.4 thou)
• 0.1mm ÷ 25.4 ≈ 0.004" (4 thou)
• 0.5mm ÷ 25.4 ≈ 0.020"
• 1.0mm ÷ 25.4 ≈ 0.039"
• 1.5mm ÷ 25.4 ≈ 0.059"

Store flat in a dry location away from direct sunlight and moisture. For very thin foils (under 0.1mm), rolling loosely and securing with a rubber band is generally recommended to prevent creasing. Avoid stacking heavy objects on top of thin sheets.
