M2 x 8mm Aluminum Knurled Thumb Screws — Flat Head, Computer Case DIY (10 Colors)

These screws are M2 x 8mm (approximately 5/16" in length). In most cases, 8mm is suitable for thin aluminum panels, side panels, or lightweight brackets up to about 4–6mm thick. If your panel is thicker, check the thread engagement depth before ordering.

Aluminum thumb screws are generally suitable for light-duty fastening tasks such as securing computer case panels, electronics enclosures, and DIY project covers. They are not intended for high-torque or structural load-bearing applications. For heavier assemblies, a steel fastener is typically recommended.

Aluminum naturally forms a thin oxide layer that provides some corrosion resistance, making these screws generally acceptable for light outdoor or humid environments. However, they are not specifically rated for marine or heavily corrosive conditions. For prolonged outdoor exposure, consider anodized or stainless alternatives.

These screws use the standard M2 metric thread (ISO 68-1), which is compatible with M2 nuts, threaded inserts, and tapped holes following the metric standard. They are not compatible with imperial #2 or UNC/UNF threads.

For a single PC case side panel, 2–4 screws are typically sufficient. For a full build with multiple panels or a DIY enclosure project, 8–10 pieces is a common choice. Buying 15 or 20 pieces is ideal if you're working on multiple builds or want spares on hand — the per-unit cost is lower at higher quantities.

Yes. The knurled outer surface is specifically designed for hand-tightening without a screwdriver or wrench. This makes them ideal for panels you open and close frequently, such as computer case side panels or access covers on DIY electronics enclosures.

Anodizing adds only a very thin layer (typically 5–25 microns) to the surface, which does not meaningfully affect thread dimensions or fit in standard M2 tapped holes. All color variants share the same M2 x 8mm specification.
