Frequently Asked Questions
What is the difference between T-shaped and L-shaped keys?
T-shaped hex key sets (unlike L-shaped keys) feature one long arm with a drive tip at the end, along with a handle for delivering more torque when rotating fasteners.
What is the difference between long end & short end handle keys?
Rotating a long end handle key delivers more torque on the fastener, as compared to using a short end handle key.
How do you maintain hex key sets?
- Protect keys from rust formation.
- Store in a dry and clean place.
- Wipe and lubricate after each use.
