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.
