Electronics assemblers, RC builders, and precision hobbyists who need fast, repeated tool-free access rely on hand-tightenable fasteners with enough grip to stay secure. These cheese head knurled thumb screws are built for exactly that — a tall cylindrical head with a deeply textured knurl surface that your fingers can grip and turn with confidence.\u003c\/p\u003e\n\u003cp\u003eEach pack contains 10 pieces. Available in thread sizes from M1.6 to M5, with thread lengths from 3mm (≈7\/64\") to 10mm (≈3\/8\"). Head diameters range from 4mm to 13mm and head heights from 3mm to 10mm depending on the variant — the full size code format is M[thread]*[length]-D=[head diameter]*[head height]. Four surface patterns are available: Black stripe, White stripe, Black reticular (crosshatch), and White reticular (mesh), all machined into the head for grip and visual identification.\u003c\/p\u003e\n\u003cp\u003eTypical applications include securing access panels on electronics enclosures, fastening battery covers and frame components on RC cars and drones, assembling 3D printer frames and optical mounts, and any DIY project where a hand-tightenable cheese head knob bolt is needed for quick-release access.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Standard ISO metric coarse threads — M1.6, M2, M2.5, M3, M4, M5.
