Review on Heavy Duty 30-Piece Hex Allen Key Wrench Set - Chrome Vanadium Steel - 15 Long Arm (Inches): 0.028”Up To 3/8" And 15 Short Arm (Metric): 0.7 Mm Up To 10 Mm With Carrying Case by Troy Meza

I had a cheaper (and smaller) set of Allen wrenches that I used for various projects. Some of them required a lot of force. Those wrenches would strip when I used them on the tougher jobs. It was frustrating to say the least, and I couldn't complete what I needed.These are solid, and have not stripped or show signs of weakness at this point. They're fairly complete for what I need to use them for around the house, bikes, etc. It's also nice to have both the metric version with the imperial in one case.I would buy again, but hopefully won't have to.
