Which drill bit for a #8 screw in hardwood? ScrewGuide answers in two taps — the complete screw, bolt and drill-bit chart with the exact pilot hole for the material in front of you, fully offline. Printed charts give you one number and hope you guessed the material right. ScrewGuide is material-aware: pick a screw, pick softwood, hardwood, MDF/chipboard, drywall, sheet metal or plastic, and it works out the pilot, clearance and countersink diameter for that exact combination — then names the nearest real drill bit you actually own, in millimetres or inches. WHAT YOU GET - The right pilot hole every time, calculated per material, so boards stop splitting and screws stop stripping - 20 screw sizes cross-referenced: metric M2-M12, US gauge #4-#14 and tapered wood screws, with major and minor diameter, thread pitch, TPI, head diameter and typical lengths - A full 68-bit drill chart in one place: metric, fractional, number and letter bits with decimal and millimetre equivalents - Measured something and don't know what it is? Dial in a diameter and get the nearest screw and the nearest drill bit instantly - A metric tap-drill chart, so you can thread a hole without hunting a reference online - Head styles and drive types decoded — Phillips, Pozidriv, Square/Robertson, Torx and hex — plus why pilot holes work at all PERFECT FOR - Woodworkers and carpenters who refuse to split another board - DIYers assembling flat-pack, hanging shelves or mounting a TV - Makers and 3D-printing hobbyists living in M3 and M4 hardware - Trades and hobby mechanics switching between metric and imperial on the same job WHY NOT JUST GOOGLE IT?
