Is 738 ft-lb enough for my car's lug nuts?

Yes for most cars and light trucks, whose lug nuts are typically tightened to 80–150 ft-lb. Loosening rusted or over-torqued nuts is where the extra headroom helps.

Does it come with a battery and charger?

Many listings sell the bare tool only. Check the box contents before ordering, since a 21V battery and charger can add significant cost.

Will it remove truck lug nuts?

It should handle most half-ton truck lug nuts, which are usually torqued to around 100–150 ft-lb. Very stubborn or rusted nuts may still need a breaker bar.

Are the batteries compatible with other brands?

No. Taskstar's 21V batteries fit Taskstar tools only and do not work with DeWalt, Milwaukee, Makita or other brands.

What size sockets does it take?

It uses standard 1/2-inch drive impact sockets. Use impact-rated sockets, not chrome hand sockets, which can crack under this torque.

When is the best time to buy it?

Cordless tools usually drop around Black Friday, Father's Day and end-of-season sales. Check the price history to see whether the current price is near its low.
