- Is 320 ft-lb enough for car lug nuts?
- Yes for most passenger cars, whose lug nuts are typically torqued to 80–150 ft-lb. It is not enough for heavy truck, tractor or rusted-seized fasteners, where 600 ft-lb and up is the norm.
- Does it come with a battery and charger?
- The listing includes one 3.0Ah 21V battery and a 23-piece set. Confirm the charger is in the box before ordering, since kit contents vary by seller.
- What does the missing NRTL listing mean for me?
- NRTL means a recognized lab such as UL or ETL tested the tool. Without it, the wrench may not pass inspection on commercial sites and has no independent electrical safety certification.
- Can I use it to remove rusted bolts?
- It will handle moderately tight fasteners, but 320 ft-lb struggles with heavily rusted or over-torqued bolts. Soak them in penetrating oil first or use a breaker bar.
- Are the batteries compatible with other brands?
- No. Untimaty's 21V packs use their own mount and are not cross-compatible with DeWalt, Makita or Milwaukee batteries. Buy a spare from the same brand.
- When is the best time to buy?
- Cordless tool kits usually drop around Black Friday, Father's Day and end-of-season clearance. Check the price history before buying to see whether the current price is above or below its usual level.
