SANDAO Allen Wrench Hex Key Set,Industrial Grade Hex Key Wrench Set Tools,L-Type+Ring Metric Hex Keys Set—CR-V Alloy Steel (8pcs). I purchased these to tighten up my dining room chairs which had been loose like forever and these instantly did it. I'm so glad I got them. It took less than one minute to tighten three chairs. Excellent! The set has every size I could ever imagine having a need for even a super skinny key that wasn't on the ring. I like the fact that they very sturdy and well made. I rarely have need for a Allan Wrench but they are nice to have when you do. And by the way, the quality of these wrenches far surpass anything I could find at Walmart. Overall I definitely recommend this to my friends and family.
