Professional insight
Mechanics match drive size to the job. They favor 6 point sockets in metric and SAE.
- 6 point sockets grip rounded bolts better than 12 point.
- Never use chrome hand sockets on an impact gun.
- Make sure common sizes like 10 mm are included.
- A fine tooth ratchet helps in tight engine bays.

Types
Hand sockets
Chrome finish, thinner walls, for ratchets and breaker bars.
Impact sockets
Black oxide or phosphate finish, thicker walls, for impact wrenches.
Deep sockets
Reach nuts on long studs, such as exhaust clamps.
Low profile sockets
Shorter than standard, for very tight spaces.
Safe use
- Seat the socket fully on the fastener before pulling.
- Pull the ratchet toward you instead of pushing.
- Wear eye protection with impact tools.
- Do not add a pipe to a ratchet for extra torque.
Common questions
- Which drive size should I buy first?
- A 3/8 inch set covers most car and home jobs.
- Do I need metric and SAE?
- Most modern cars use metric. Older US vehicles may need SAE.
- Is a 12 point socket bad?
- No. It engages every 30 degrees, which helps in tight spots.
