#6-32 Aluminum Anodized Thumb Screws – Knurled Hand Bolt for PC Case Modding & DIY

Measure the total thickness of the panels or material you need to fasten, then add typically 3–5mm for thread engagement. For example, a standard PC case panel is generally 1–2mm thick, so a 6.5mm (≈1/4") screw is usually sufficient. For stacked panels or thicker brackets, consider 10mm (≈3/8") or 12mm (≈1/2"). When in doubt, size up — a slightly longer screw with a nut or standoff is more forgiving than one that's too short.

These thumb screws are made from aluminum alloy with an anodized color finish. Anodizing is an electrochemical process that hardens the surface and bonds the color directly into the metal, making it generally more durable and scratch-resistant than paint or plating.

Aluminum naturally forms a protective oxide layer, giving it good corrosion resistance in most indoor and mildly humid environments. The anodized finish adds an additional layer of protection. However, for prolonged outdoor exposure or salt-spray environments, a stainless steel fastener is generally a better choice. Contact us to confirm suitability for your specific application.

These are #6-32 UNC (Unified National Coarse) thread screws, which is the most common thread standard used in PC cases, server chassis, and electronics enclosures in North America. They are compatible with standard #6-32 threaded standoffs, nuts, and captive nuts found in the vast majority of ATX, Micro-ATX, and Mini-ITX cases.

As aluminum thumb screws designed for hand-tightening, these are typically used for light-duty panel retention, side panels, drive bay covers, and decorative or access covers — not for structural load-bearing joints. For applications requiring high clamping force, a tool-driven steel fastener is generally recommended. Contact us to confirm load requirements for your specific use case.

Yes. These #6-32 knurled thumb screws are widely used beyond PC builds — including electronics project enclosures, rack-mount equipment, custom aluminum panels, DIY synthesizer builds, and maker/fabrication projects. Any application that uses #6-32 threaded holes and benefits from tool-free access is a good fit.

Anodized finishes are generally more durable than painted or powder-coated surfaces because the color is integrated into the aluminum oxide layer rather than sitting on top. Under normal indoor use, fading is typically minimal. Heavy abrasion or contact with harsh chemicals may wear the finish over time.

These are available in packs of 1, 10, or 50 pieces. A single-piece order is ideal for testing fit or replacing a lost screw. A 10-pack suits most PC builds (typically 4–8 screws per side panel). A 50-pack is cost-effective for modders, makers, or small shops that work on multiple builds or enclosures.
