Start with the task. Removing trim, undoing a nut and tightening to a specified torque require different tools.
Task → suitable tool
1
Trim: a plastic removal tool
2
Fastener: matching socket and wrench
3
Specified torque: a torque wrench
What to do, step by step
Describe the task
For example: 'remove a door trim panel' or 'tighten wheel bolts'. Photograph the fastener if you do not know its name.
Check size and contents
The socket must match the nut. Socket and ratchet drive squares must be the same size. Batteries and chargers may be sold separately.
Confirm safe use
Use the vehicle's documented tightening torque rather than guessing. Work beneath a car requires suitable stands. Never work beneath a car supported only by a jack.
More detail and common mistakes
- Record fastener sizes, profiles and access constraints. Socket, ratchet and extension drives must match. Impact tools require suitable impact-rated accessories.
- Check the box contents. Batteries, chargers, adapters and consumable accessories may be absent. Match an air tool's requirements to compressor capability.
- Use documented tightening torque. Work beneath a vehicle requires properly rated stands and correct lifting points. Never work under a vehicle supported only by a jack.
