Community Reviews

This compact folding Klein hex key set is best for keeping SAE, metric, and Torx bits organized in a small, neat package for occasional household use. The folding design is praised for reducing flex compared with some other 90 degree tools, and the lifetime warranty adds peace of mind. The main tradeoff is thickness and durability, since the keys are not removable and may not fit tight spots. Reports also point to loosening, stripping, and Torx wear under harder use, so it suits lighter tasks better than heavy work.

  • The folding hex keys can help keep a hex drawer organized and tidy.

  • The 7 or L-shaped design can reach set screws that thicker tools cannot.

  • The set can work well for smaller manual tasks when thread lock is used.

  • The folding style may minimize flexing and loosening compared with some similar sets.

  • The folding keys are not removable, which can limit access in tight setups.

  • The compact folding design may not fit where slim keychain-style Allen wrenches fit.

  • The set can require constant tightening and may strip easily under use.

  • Durability can be poor, including nut backing off and twisted T15 Torx flutes.

Do these tool handles flex from force when being used at 90-degree right angle? Or do they have a metal body?

I have those...they're the reason I just bought this Klein set.
What seems to be the issue with the HFT ones?

Flimsy. One set exploded from the nut backing off. The flutes on the T15 Torx twisted. They would be OK for occasional homeowner use but definitely not anything more than that.

Yea i did put thread lock on my set but that's about it, so I never had any issues. I use them for work and while they seem fine for some smaller pattycake manual work, anything serious I use a driver or right angle drill. FYI they have a lifetime warranty no questions asked replacement on all HFT hand tools, should you ever need it.

I have these, they need constant tightening. They also strip pretty easy.

If you've ever used this style tool, exactly what he's asking. At a 90 degree angle some tools like this tend to flex and then in turn loosen up. I have a craftsman set that does this.
To aid in answering, i have found the Klein's to minimize this. I'm in for a cheap set. Thanks OP 👍🏼
