KNIPEX Tools 00 20 06 US2, Pliers Wrench 3-Piece Set

The Verdict

Opening Hook

If you’ve ever crushed a brass fitting with an adjustable wrench or rounded off a bolt head with a worn-out pair of pliers, you already know the pain. The KNIPEX Pliers Wrench 3-Piece Set is the tool that makes those problems vanish. This is the set that professional plumbers, electricians, and machinists quietly hoard — and with a 4.9/5 rating from 245 buyers, it’s not hype. It’s a precision instrument that replaces half your toolbox.

What You Actually Get

This set includes three sizes: 6-inch (0 0 20 06), 10-inch (0 0 20 10), and 12-inch (0 0 20 12). All three share the same DNA: a smooth, parallel jaw that grips like a wrench but adjusts like pliers. The 10:1 gear ratio means you can fine-tune the jaw opening with a thumb flick, even while holding the tool mid-air. Each wrench has a push-button release on the top — press it, slide the jaw open, and you’re ready for the next fastener. The jaws are induction-hardened to 56-60 HRC, and the body is chrome vanadium steel, so they’ll outlast your grandkids’ hobby projects.

Performance and Build Quality

The magic here is the parallel jaw. Unlike a crescent wrench, which applies force to two corners of a hex nut, the KNIPEX jaw makes full flat contact with all six sides. That means you can clamp down on a polished chrome faucet nut without leaving a single scratch — and still apply enough torque to break it loose. On the 12-inch model, you’re looking at a rated clamping force of over 3,000 pounds. That’s not a typo.

In real-world use, I’ve seen these replace three separate tools: a pipe wrench (for clean, non-marring work), an adjustable wrench (for speed), and a set of locking pliers (for stubborn fasteners). The adjustment mechanism doesn’t slip — there’s no ratcheting detent to wear out, just a smooth worm gear that holds position under load. One buyer put it plainly: “I’ve used these daily for three years. The 10-inch has become my go-to for 90% of my work. The grip is so secure, I’ve stopped carrying a crescent wrench entirely.”

What Buyers Consistently Praise

The recurring theme in 245 reviews is the “no-mar” grip. A homeowner wrote: “I replaced a bathroom faucet without scratching the chrome once. My old adjustable wrench would’ve left gouges.” Pros love the time savings: “I can switch between 1/2-inch and 3/4-inch hex heads with one hand while holding a pipe in the other. It’s stupid fast.” Another reviewer noted the set’s durability: “I dropped the 12-inch off a 12-foot ladder onto concrete. It landed on the jaw, and it still works perfectly. No bend, no chip.”

Where It Falls Short

Honestly? The handles. They’re bare steel — no rubber grips, no cushioning. If you’re cranking on a seized bolt for ten minutes straight, the sharp edges will dig into your palm. Wear work gloves or accept the fatigue. Second, the 6-inch wrench is almost too small for general use. It maxes out around a 1-inch jaw opening, which means it’s great for electrical work and small fasteners, but useless for plumbing. You’ll reach for the 10-inch 80% of the time. Third, the price. Each wrench costs roughly what a mid-range adjustable wrench does — but you’re paying for precision. If you only need one size, buy the 10-inch alone. The set is for people who work across multiple trades.

Who Should Buy This

• The weekend DIYer who’s tired of rounding off bolts and scratching fixtures. This set will last you decades and make you look like you know what you’re doing.
• The professional plumber or electrician who needs a reliable, non-marring grip for finishing work. The 10-inch and 12-inch will become your daily drivers.
• The machinist or mechanic who works with tight tolerances and needs a tool that won’t slip on precision fasteners.

Skip it if you only need a single wrench and don’t want to spend for three, or if you need a hammer — these are not that.

FAQ

Q: Can these replace a pipe wrench for stuck fittings?
A: Yes, for clean, non-marring work on hex or square fittings. But for rounded, corroded pipe, a traditional pipe wrench’s teeth will bite harder. Use KNIPEX first, pipe wrench as backup.

Q: Do the jaws stay parallel at full extension?
A: Yes. Even at maximum opening, the jaw faces remain perfectly parallel. That’s the key difference from a crescent wrench.

Q: Are these made in Germany?
A: Yes. The set is manufactured in Wuppertal, Germany, under ISO 9001 quality standards.

The Verdict

Buy it if you want a precision tool that replaces three others, protects your workpieces, and will survive a decade of abuse. Skip it if you’re on a tight budget and only need one size — grab the 10-inch alone instead.

This is the rare 4.9-star product that earns every star. The only deduction is for the handle comfort and the occasional uselessness of the 6-inch size. At 4.6/5, it’s a justified score. Your hands will thank you.
