If you've ever struggled to tighten or remove case screws without a screwdriver during a late-night build or quick component swap, these aluminium alloy thumb screws are the fix you've been looking for. Designed for PC builders, modders, and workshop enthusiasts who need fast, hand-tightened fastening without reaching for tools.
Each thumb screw features a flat knurled head for a secure finger grip, machined from aluminium alloy in metric thread sizes M5 and M6. Thread lengths range from 10 mm to 20 mm (approx. 0.39 in to 0.79 in), with a head diameter typically 14–20 mm (0.55–0.79 in). Available in seven anodized color options: Red, Silvery, Green, Blue, Golden, Black, and Sky Blue.
Ideal for tool-free computer case panel fastening, DIY electronics enclosures, 3D printer frame assembly, and lightweight aluminium bracket mounting. The metric thread sizing makes these a reliable choice for aluminium alloy thumb screws M5 M6 computer case builds and maker workshop projects.
Flat knurled head design allows firm finger grip for quick installation and removal without any tools — ideal for frequent access panels.
Available in both M5 and M6 metric thread diameters, covering the two most common sizes used in PC cases and DIY enclosures.
Choose from Red, Silvery, Green, Blue, Golden, Black, or Sky Blue to match your build aesthetic or color-code different panel sections.
Machined from aluminium alloy for a balance of strength and low weight — won't add unnecessary mass to lightweight builds or portable enclosures.
Order in packs of 1, 5, 10, 20, or 50 pieces to match your project scale — from a single replacement to a full workshop stock-up.
Thread lengths from 10 mm to 20 mm (0.39–0.79 in) accommodate varying panel thicknesses and standoff depths across different enclosure types.

Check the threaded insert or nut in your computer case or enclosure. M5 has a 5 mm thread diameter and M6 has a 6 mm diameter. Most standard ATX and mATX cases use M3 or M6 standoffs, while some aluminium enclosures use M5. If unsure, use a thread gauge or compare against an existing screw from your case.
Measure the depth of the threaded hole or standoff, then add the panel thickness. The thread length should be equal to or slightly shorter than this combined depth to avoid bottoming out. For typical PC side panels (1–2 mm), a 10–12 mm thread length is usually sufficient.
Yes. These are Grade 5 aluminium alloy thumb screws, which provide adequate tensile strength for panel fastening, enclosure assembly, and light-duty bracket mounting. They are not intended for high-torque structural applications. For hand-tightened panel screws, they perform reliably under normal use.
Anodized aluminium finishes are more durable than paint and resist chipping under normal handling. However, repeated heavy abrasion or contact with harsh chemicals may wear the finish over time. For decorative builds, handle with care during installation to preserve the color.
Aluminium alloy naturally forms a protective oxide layer, giving it good resistance to light corrosion in typical indoor environments. The anodized finish further enhances this protection. These screws are not recommended for outdoor or high-humidity applications where stainless steel would be more appropriate.
Yes. M5 and M6 thumb screws are commonly used in 3D printer extrusion frames, aluminium electronics enclosures, and maker project boxes. Confirm the thread pitch of your frame's T-nuts or inserts matches standard metric coarse pitch (M5×0.8 or M6×1.0) before ordering.
Most ATX cases use 4–8 thumb screws for side panels and 2–4 for the top or front panels. A 10-piece pack covers a standard dual-panel build, while a 20-piece pack is ideal if you're also securing drive cages or expansion slot covers. The 50-piece pack suits workshop stock or multi-system builds.
