Do I need sockets separately, or are they included?

The wrench itself is included with the case. Sockets are not — you'll pair this with your own 1/2" socket set, which gives you flexibility to use what you already have on hand.

How do I reset the wrench after use?

After you're done for the day, loosen the adjustment knob back to the lowest setting. This keeps the internal spring relaxed and extends the wrench's accuracy over time.

Will this wrench work for engine head bolts and suspension work?

Yes. The 10–60 N·M range covers both — head fasteners typically sit mid-range, and suspension bolts usually land at the lower end. One wrench handles both jobs without switching.
