• 📐 M3 ALUMINIUM KNURLED THUMB SCREWS — FLAT HEAD, 10MM KNURLED GRIP — Thread M3, available in 10mm and 15mm lengths. Flat head design sits flush against panels and surfaces for a clean, low-profile finish. Knurled head precision-cut for secure finger grip — fast hand-tightening and removal without tools. Available in 5 or 10 piece packs.
• 🏭 CNC MACHINED FROM SOLID ALUMINIUM 7075 — MADE IN THE EU — Every screw is precision-turned from high-grade aluminium 7075 billet in our European workshop. Available in Natural Aluminium and Black Anodised finish. Hard anodised surface is bonded into the metal — resistant to scratching, corrosion and wear. Approximately 70% lighter than equivalent steel screws.
• 🔧 DESIGNED FOR 3D PRINTING, ELECTRONICS, RC MODELS AND ENCLOSURES — Ideal for any application requiring fast, repeated tool-free access: 3D printer panels and covers, electronics enclosures, RC model body panels, custom PC cases, guitar pedal boards and any project using M3 threaded inserts or tapped holes in aluminium, steel or acrylic.
• 🎨 NATURAL ALUMINIUM OR BLACK ANODISED — TWO DISTINCT FINISHES — Natural finish delivers a classic machined aluminium look with visible tooling character. Black Anodised offers a sleek, modern aesthetic ideal for dark builds and premium enclosures. Both finishes are hard anodised — bonded into the surface, not painted or coated, for lasting durability.

Fully compatible with standard M3 nuts, brass threaded inserts, steel inserts and tapped holes in aluminium, steel, acrylic and wood. No tools required for installation or removal.
