Never guess a bolt size again. The Woinex ThreadIQ™ instantly identifies 30 nut and bolt sizes — 15 metric and 15 standard. Rustproof SUS304 steel studs. CNC-machined 6061 aluminum base. Built-in inch and cm rulers. Hangs right on your wall, ready when you need it.


Stop guessing. Start matching.

That junk drawer full of loose bolts just became useful. The Woinex ThreadIQ™ tells you the exact size of any nut or bolt in seconds.

Each size has a male stud for checking nuts and a female thread for checking bolts. Just thread it on. The size is laser-etched right next to it. No charts. No calipers. No second-guessing.

Covers 30 of the most common sizes — 15 metric (M3 to M14) and 15 standard (#4-40 to 1/2-20). Built to the Go & No-Go Class 2B ANSI standard, so every match is accurate to ±0.002".

✅ 30 sizes — 15 metric + 15 standard
✅ Male + female threads for nuts AND bolts
✅ Rustproof SUS304 stainless steel studs
✅ Anodized 6061 aluminum base — won't bend or crack
✅ Inch and cm rulers on both edges
✅ Two hanging holes for wall or pegboard
✅ Laser-etched labels that never wear off

Perfect for your garage, workshop, job site, or toolbox.

  • I had a coffee can full of random bolts sitting in my garage for years. Sorted the entire thing in one evening with this. The labels are crisp and the studs are solid steel, not the cheap hollow kind. Best upgrade my workbench has had in a long time.

  • Way more heavy duty than I expected. The base does not flex at all and the threads grab clean every time. It hangs right on my pegboard so it is always within reach. No more guessing bolt sizes.

  • I used to drive to the hardware store just to match a single bolt. Now I check it at home in about ten seconds. It does metric and standard on the same tool, which is perfect since I work on both imports and domestics.

    How It Works

    The Woinex ThreadIQ makes matching hardware simple. Grab any loose nut or bolt and thread it onto the gauge. Use a male stud to size your nuts and washers, or a female hole to size your bolts and screws. The exact size is laser etched right next to each thread, so you read your answer in seconds. It covers 30 of the most common sizes, 15 metric and 15 standard, and every thread meets the Go and No Go Class 2B ANSI standard for accuracy within 0.002 inches. Built in inch and centimeter rulers on both edges let you measure bolt length too.

    Machined 6061 Aluminum Base
