Frequently Asked Questions (FAQs)
1. Is there a difference between Allen keys and hex keys?
The short answer is “there is no difference”. Really, these two names can be used interchangeably.
2. What is the strongest material for Allen keys?
Material. An Allen wrench set made of heavy-duty steel or alloy like chrome vanadium steel will be durable enough to last for years of use. If you pick a different low-grade material, the keys might bend or the edges might wear into a circle over time.
3. What can I use instead of a hex key?
Socket Wrench or Ratchet Wrench If you have one that will fit in the hex screw hole or hexagonal socket you are working with, a socket wrench may come in handy in place of an Allen wrench.
4. Are hex keys hardened?
A good quality hex wrench is characterized by toughness, and that typically means it's been heat treated to harden and tempered. Keep in mind this is what makes metal strong without being brittle, so your Allen wrench will offer a superior experience in high torque applications.
