What is the difference between velocity and lightning?

Why the name change?

Question: What is the difference between Velocity Screws and Lightning Screws?

Answer: They are the same screw!

Question: Why then did you change names?

Answer: Our screws are all about helping the user spend less time fumbling around with  their fastener. In other words, it is all about speed. The name Lightning was chosen as we believed it would convey the benefit of speed ... as in lightning fast. But after testing the name and having conversations with hundreds of users, we discovered that the name wasn't conveying speed. We tested several new names and found that "Velocity" did the best.
