How to Use Basic Tools
Before you turn a single bolt, you need to know what's in your hand. This lesson walks through the 10 tools every beginner mechanic should own, how to actually use them without rounding off bolt heads or stripping screws, and the safety habits that keep your fingers attached.
The lesson
Wrenches & Sockets
Wrenches come in metric (mm) and SAE (inches). Most modern cars use metric. A 3/8" drive socket set with sizes 8mm-19mm covers 80% of jobs. Always pull a wrench toward you — never push, or you'll bust your knuckles when the bolt breaks free. Six-point sockets grip better than 12-point and are less likely to round off a worn bolt head.
Pliers — the right kind
Slip-joint pliers for grip. Needle-nose for tight spots and electrical work. Channel-locks for plumbing-style grips. Never use pliers on a hex nut if a wrench fits — you will strip it. Lineman's pliers handle thicker wire; diagonal cutters ('dikes') flush-cut zip ties and small wire.
Screwdrivers
Phillips (cross) and flathead are the basics. Match the size exactly. A #2 Phillips in a #1 screw will cam out and chew the head. Quality matters here — cheap drivers strip on day one. JIS (Japanese) screws look like Phillips but aren't — JIS drivers fit better on Japanese cars.
Torque Wrench
Critical for wheels, head bolts, and any spec'd fastener. Set it to the manufacturer's torque value (in ft-lbs or Nm). Click-type wrenches click when you hit the target. Don't use it to break bolts loose — only to tighten. Always store a click-type wrench backed off to its lowest setting; storing it tight ruins the spring.
Jack & Jack Stands
Floor jack lifts. Jack stands hold. Never — ever — work under a car held up by only a jack. People die that way. Use jack stands on the frame, not the floor pan or plastic. The factory jack points are marked in your owner's manual; using the wrong spot will bend the unibody.
Eye protection, gloves, and the dropcloth
Safety glasses every time — rust flakes and degreaser spray will blind you. Mechanic's gloves prevent knuckle cuts and chemical burns. A cheap moving blanket on the floor saves your back and catches dropped fasteners before they roll under the car forever.
Tool list

- Combination wrenches (10-19mm)
- Needle-nose, slip-joint, and channel-lock pliers
- Phillips #1, #2 + flathead screwdrivers (JIS for Japanese cars)
- Click-type torque wrench (1/2" drive, 10-150 ft-lb)
- 2-ton floor jack + (2) jack stands rated above vehicle weight
- Wheel chocks
- Safety glasses + mechanic's gloves
Safety — Read or get hurt
- !!Always chock the wheels opposite the side you're lifting.
- !!Use jack stands on a flat, hard surface. Never on grass, gravel, or asphalt in summer heat — the stands sink.
- !!Eye protection is not optional. Rust flakes fall.
- !!Don't wear loose sleeves, rings, watches, or chains near rotating parts — degloving is real.
- !!Store click-type torque wrenches at lowest setting to preserve calibration.
