FAQ

Q1: What is the difference between Breakaway Torque (420Nm) and Fastening Torque (356Nm)?
A1: Fastening torque (up to 356Nm) is the force used to tighten bolts, while breakaway torque (420Nm) is the short burst of power used to break loose stuck, over-tightened, or rusted nuts.

Q2: Can this impact wrench remove automobile wheel lug nuts?
A2: Yes! With 420Nm of breakaway torque and a 1/2″ square drive, it easily removes lug nuts on passenger cars, SUVs, and light commercial vehicles.

Q3: What bolt sizes is this wrench designed for?
A3: It is recommended for standard bolts from M12 to M18 and high-tensile bolts from M12 to M16.

Q4: Why is the 1.1kg weight significant?
A4: At only 1.1kg (bare tool), it is significantly lighter than traditional 1/2″ impact wrenches, making it much easier to use overhead or in tight engine bays without causing arm fatigue.

Q5: Are samples available before placing a bulk order?
A5: Absolutely! We welcome sample orders so you can evaluate the build quality, torque output, and ergonomics before placing mass orders.
