Questions and answers

Is the W3151 worth it at $239.99?
At $239.99 at Tractor Supply Company as of November 3, 2026, it is priced at the bottom of its recent range. With two batteries and 450 ft-lbs breakaway, it is a fair value for a compact 20V wrench.
How does it compare with a full-size high-torque impact wrench?
It is smaller and lighter but rated at 320 ft-lbs fastening versus 700 ft-lbs and up for full-size corded or 60V-class tools. Use it for most car and light-truck fasteners, not for heavy equipment.
How long do the 2.5 Ah batteries last?
Expect roughly an hour of mixed lug-nut and light assembly work per pack. Heavy continuous use on seized bolts will drain a pack much faster, which is why two are included.
What size sockets does it take?
It has a 1/2-inch square drive with a friction ring, so standard 1/2-inch impact sockets fit. Use impact-rated sockets only.
What comes in the box?
The tool, two 20V 2.5 Ah lithium-ion batteries and a charger. Confirm the exact kit contents with the store before ordering.
When is it cheapest?
Cordless tool prices drop around Black Friday and spring contractor events. The current $239.99 is already near the low end of its recent range, so waiting may not save much.
