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 didnít stop there. They increased the value by including two wrenches in one allowing compatibility with any 4 to 5mm turnbuckle.


  • 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

Tekno RC Hardened Steel Turnbuckle Wrench (4mm & 5mm)
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.

Tekno RC Hardened Steel Turnbuckle Wrench (4mm & 5mm)
great tool. The aluminum losi one stripped out in a few months of use, this is still going strong almost 2 years now

Tekno RC Hardened Steel Turnbuckle Wrench (4mm & 5mm)
These Tekno wrenches are awesome. I bought both sizes (as well as the shock pliers and 17mm wheel wrench) a couple months ago when I bought 3 Tekno kits. They come in so handy with not only adjusting the turnbuckles, but also building them. There are far more uses for them and like every thing Tekno makes, their tools are great quality. Tekno fan for life!
