When you're mid-build and reaching for a screwdriver just to secure a panel feels like one step too many, thumb screws are the answer. These M6x14 knurled flat head thumb screws are designed for makers, PC builders, and workshop enthusiasts who need fast, repeatable hand-tightening without sacrificing a secure hold.
Each screw is machined from aluminium alloy with a black anodised finish, giving it both a sleek appearance and a layer of corrosion resistance. The thread diameter is M6 (6mm / ~0.236 in) with a shank length of 14mm (~0.551 in). The knurled flat head provides a wide, textured grip surface for confident finger-tightening even in tight spaces.
Ideal for PC case panel fastening, electronics enclosures, 3D printer frame assembly, and custom fabrication jigs — anywhere you need M6 thumb screws for tool-free access panels or quick-release mounting points in aluminium or steel structures.

A standard ATX PC case typically uses 4–6 thumb screws for side panels. If you're building a single PC, the 5pcs or 10pcs pack covers most builds with spares. For workshop stock or multiple builds, the 50pcs pack offers the best per-unit value. Select your pack size from the Packing Qty option above.
Yes. Aluminium alloy thumb screws at M6 size provide sufficient clamping force for panel retention in PC cases and electronics enclosures. They are not intended for high-torque structural applications — for those, steel fasteners are recommended. For panel access and light-duty mounting, these deliver reliable hold under normal use.
The anodised coating forms a hard aluminium oxide layer that is more wear-resistant than bare aluminium and provides good resistance to light corrosion and humidity. It is not impervious to heavy abrasion or harsh chemical exposure. For indoor PC and electronics use, the finish holds up well over repeated installation and removal cycles.
Yes. These screws use a standard M6 metric thread and are compatible with M6 captive nuts, cage nuts, and threaded standoffs commonly found in ATX, mATX, and ITX PC cases, as well as server rack panels and electronics enclosures. Always verify your case uses M6 (not M3 or M5) threads before ordering.
Yes. These thumb screws work with any panel material that has a compatible M6 threaded hole or captive nut — including aluminium, steel, and acrylic. For acrylic panels, hand-tighten carefully to avoid cracking the material around the hole; do not over-torque.
Standard hex head bolts require a wrench or socket for installation and removal. These knurled flat head thumb screws are designed for tool-free hand operation, making them ideal for panels you open frequently — such as PC side panels, filter covers, or access doors. The flat knurled head also sits flush or near-flush for a cleaner appearance.
Yes, M6 thumb screws are widely used in 3D printer builds (particularly those using aluminium extrusion frames with M6 T-nuts) and in custom fabrication jigs where quick tool-free adjustments are needed. Confirm your extrusion or jig uses M6 thread before purchasing.
