Frequently Asked Questions about Standard and Impact Ratchets

What is the main difference between an impact wrench and a standard ratchet?

An impact wrench delivers torque through concussive, rotating hammer blows, making it ideal for breaking loose stubborn fasteners. A standard power ratchet provides smooth, continuous rotation for controlled tightening and assembly. The impact mechanism creates significantly higher burst torque with less user strain.

This fundamental difference dictates their use: impacts excel at disassembly, while standard ratchets are perfect for precision work and running fasteners down without cross-threading.

Can you use a standard socket on an impact wrench?

No, you should never use a standard chrome socket on an impact wrench. Standard sockets are hardened but brittle and can shatter under the hammering force. This creates a serious safety hazard from flying metal fragments.

Always use impact-rated sockets, which are typically black. They are made from a tougher, more ductile alloy that can absorb the repeated shock loads without fracturing.

How do I choose the right drive size for my needs?

Choose the drive size based on the fastener size and torque requirements of your typical projects. For most automotive and DIY work, a 3/8″ drive offers the best balance of versatility, power, and socket availability. It handles a wide range of bolt sizes.

Use 1/4″ drive for small, delicate fasteners in electronics or trim. Reserve 1/2″ drive for high-torque applications like truck lug nuts, axle bolts, and heavy machinery where maximum power is essential.

What is better for removing lug nuts: impact wrench or ratchet?

An impact wrench is vastly superior and safer for removing lug nuts. Its pulsed torque breaks the lug’s corrosion seal efficiently and minimizes the strain on your wrists and arms. A standard ratchet often lacks the power and risks damaging its motor on seized lugs.

For final installation and torquing to specification, however, you should always use a calibrated torque wrench. This ensures even clamping force and prevents warping brake rotors.

Why is my impact wrench not loosening a bolt?

If your impact isn’t loosening a bolt, first ensure you have sufficient air pressure or battery charge. Try using a penetrating oil and letting it soak to break corrosion. The fastener may also be exceeding your tool’s torque rating, requiring a larger 1/2″ drive model.

Check that you are using the correct direction setting (left for loosen). For extremely stubborn bolts, applying controlled heat with a torch to the surrounding nut can expand the metal and break the bond.

Are brushless power ratchets worth the extra cost?
