What size torque wrench should I buy first?

1/2-inch click for lug nuts if you change wheels. 3/8-inch click if you are starting with brakes and engine accessories. Most garages end up with both, plus an inch-pound wrench for small fasteners.

Should I buy a click or digital wrench first?

Click first. Digital when you need a live number, unit switching, or angle. Digital is a poor first wheel wrench because it is easy to overshoot while kneeling in a driveway.

Can I borrow a torque wrench from AutoZone?

Often yes, with a deposit. Fine for a one-off. If you rotate tires or work on engines more than twice a year, own a wrench you can store at its lowest setting.

For home garages

Pick a torque wrench for the job in front of you

Start with the fastener, not the brand on the box. Match the drive to the spec, pull once to the click, then wind the wrench down before it goes back in the drawer.

Choose by the fastener

Stores will sell you a wrench. They will not tell you that a 1/2-inch 250 ft-lb clicker is the wrong tool for a valve cover. Start with the job, then buy for that job.

One click is the measurement

Set the scale, lock the collar, pull straight, and stop at the first click. Then wind a click wrench down to its lowest marked setting. How to use one covers that in order.

If you shop by brand

Harbor Freight sells three different lines, not one wrench. Milwaukee’s click tools are not impact wrenches. Snap-on is sold off a truck. If that is how you already shop, start with the brand, then come back to drive size.

Common questions

Yes, whenever a fastener has a published spec. Wheels, suspension, and engine bolts are the usual reasons. A $40 click wrench is cheaper than a stretched stud or a warped rotor.
