Have you ever used a setscrew when working on your bike?

Yeah, I had to tighten one to keep the handlebars from moving.

That makes sense; I should probably check mine, too.

Definitely! A loose setscrew can really mess up your ride.

Root Explanation

**Setscrew** → The word is formed from "set" (from Old English *settan*, meaning to place or put) and "screw" (from Old French *escroue*, meaning a metal fastener). A setscrew is a type of screw that is used to secure an object in place, hence the combination of placing and fastening.

Memory Tip

Think of 'placing' something ('set') securely with a 'fastener' ('screw') — that's what a setscrew does.
