About this part

This is a Tekno RC Hardened Steel Turnbuckle Wrench, with 4mm and 5mm ends. The current crop of aluminum turnbuckle wrenches wear out easily and are bulky to compensate for their weakness. This makes it hard to fit into tight places. There are more durable steel wrenches out there too, but they are expensive and can be uncomfortable to use.

So the guys at Tekno made a hardened steel turnbuckle wrench that is durable, fits into the tightest places, and is comfortable to use.  But they didn’t stop there. They increased the value by including two wrenches in one allowing compatibility with any 4 to 5mm turnbuckle.

Features:

  • Hardened steel CNC production
  • Black coated to help prevent rust
  • Laser etched size indications (4mm, 5mm)
  • Comfortable and easy to use
  • Compatible with any vehicle that uses 4 or 5mm turnbuckles

This little wrench is worth every penny! I became very tired of using needle-nose pliers on the turnbuckles, slipping and sliding all over the place. This very simple tool is solid and I don't know how I lived without it.

great tool. The aluminum losi one stripped out in a few months of use, this is still going strong almost 2 years now

Very light, easy to use, I bought both turn buckle wrenches and find them with high quality you would expect from tekno. You won't be disappointed!

I originally owned the EcoPower 6 in 1 turnbuckle wrench and I would easily spend 2x-3x or more money again to have these ones. They feel like a real tool, giving you a real grip on adjustments. If you are the type to spend more money on MIP drivers, you will want the Tekno turnbuckle wrenches. A+

What reviewers say

All six reviewers give the Tekno hardened steel turnbuckle wrench (4mm and 5mm) five stars. Reviewers say it grips turnbuckles far better than needle-nose pliers, feels solid and well made, and is light and easy to use. One reviewer reports it has lasted almost two years, after an aluminum competitor stripped within months. Some reviewers mention buying both sizes and note extra uses such as building turnbuckles. No reviewer reports a problem or disagrees with the others. The sample is small and most reviews are brief.

  • + Better grip than needle-nose pliers
  • + Solid, hardened steel construction
  • + Long-lasting, outlasted aluminum competitor
  • + Light and easy to use
