Tool & Hardware Dict

Tools by job, sizes by spec

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

"#8" is not M8. A Phillips bit cams out of a Pozidriv screw. CAMI 600 is not FEPA P600. Fourteen charts, every number sourced, inch and metric side by side. Look up the job you want to do, and get the tools and the steps for it. "Put up a shelf." "Stripped screw head." Search by the name of the job, the tools you need line up, and you can jump straight into how each one works. ■ Look up by the job (63 jobs, all free) Put up a shelf on a wall. Cut a board straight. A stripped screw that just spins. Clean a vent fan. Fit anti-topple brackets to a bookcase. Each one lists the tools and the steps, and 30 of them add "Where it goes wrong" — the one point that catches people out even when they follow the steps. Example: a TV must not be mounted to drywall alone. You need a stud, or anchors rated for the load. ■ Size charts (14 charts, 114 rows, every one sourced) This is the heart of the app. If a number is printed here, so is where it came from. Numbers we could not source are not in the app at all. "#8" is not M8. A #8 wood screw is 4.17mm and M8 is 8.00mm — nearly double, and confusing the two is the most common mistake there is. Put a Phillips bit in a Pozidriv screw and it goes in, then cams out and chews the head. Four fine tick marks at 45° to the cross means PZ. The same "600" is not the same coarseness: CAMI 600 (16μm) matches FEPA P1000, not the FEPA grade with the matching number. A 3/16" hex key is 4.76mm, close enough to 4mm to round out a socket. • Inch hex bolts across flats (ASME B18.2.1) • Inch hex keys for cap screws (ASME B18.3) — and why a set screw of the same size takes a smaller key • Screw drives compared: Phillips, Pozidriv, Torx, Robertson • US nail sizes (penny size) — why 10d common and 10d box are different thicknesses • Inch wood screw gauges (US gauge) with pilot holes for softwood and hardwood • Sandpaper grit conversion between CAMI and FEPA The Japanese standards are here too, for when a Japanese tool or fastener is the thing in your hand: Phillips driver sizes (JIS B 4633), hex keys (JIS B 1176), wrench and socket flats (JIS B 1180), nails (JIS A 5508), pilot hole diameters and coarse-thread screw lengths. ■ Tool reference (90 tools, each illustrated) What it is for, the safety notes, how to choose one. All 12 power tools and all 9 cutting tools carry safety notes, with no exceptions. From a tool you can reach the charts that apply to it and the other tools in its category. Job → tool → size runs as one thread. ■ Nine languages English, Japanese, German, French, Italian, Spanish, Portuguese, Simplified Chinese, Traditional Chinese. Tool names are not translated literally. We use the name that works at the counter: diagonal cutters, not "nippers"; an adjustable wrench, not a "monkey wrench", which is a different tool. A try square and a carpenter's square stay two separate entries, because they are two separate tools. ■ One-time purchase. No ads. No network. The job lookup, how to use each tool, the safety notes, the size charts, search and favourites are all free. The one-time Pro unlock adds the "how to choose it / pro tips" notes on each tool. It is not a subscription. There are no ads. The app never connects to anything. All of the data ships inside the app, so it opens on a site with no signal.
