Stanley 250mm 3/8" Drive CrV Steel Extension Bar

Material: chrome vanadium steel (CrV). Length: 11 inches. Drive size: 3/8". Finish: smooth black coat for durability and corrosion resistance. Compatibility: designed to work with Stanley 3/8" drive tools.

It is compatible with 3/8" drive sockets and ratchets, and specifically works with Stanley 3/8" drive tools. It can also seat in 3/8" drive sets from other brands that use the same drive size.

Use it to extend reach for bolts in engines, machinery, automotive work, or any job where the fastener is tucked away or obstructed by components.

1) Attach the extension bar to a 3/8" drive ratchet. 2) Attach a compatible 3/8" drive socket to the other end. 3) Use the setup to reach the fastener in your workspace, applying torque as needed. 4) After use, detach and store properly.

The 11-inch length provides additional reach beyond a standard extension, allowing you to access bolts that are recessed or blocked by components while still enabling leverage and control.

Compared to a 1/4" drive extension bar, this 3/8" drive model offers greater socket size compatibility and higher torque capacity for medium-duty tasks. Compared to a 1/2" drive extension bar, the 3/8" version is better suited for mid-range sockets and more compact spaces.

Keep it clean and dry after use. Wipe away dirt or moisture, and apply a light coating of oil if you expect prolonged storage to prevent rust. Store in a dry place away from corrosion-causing elements.

Ensure the socket and extension bar are properly seated on the ratchet and fastener. Do not use the bar as a pry tool or lever for prying actions. Use appropriate PPE (gloves, eye protection) as needed and avoid exceeding the torque capacity of your ratchet, socket, or fastener.

If the socket doesn’t seat properly, re-align the connection between the extension bar, socket, and ratchet. Inspect for any bending, cracks, or corrosion—if damaged, replace. Ensure you’re using the correct 3/8" drive components to avoid fitment issues.

Yes. The chrome vanadium construction and the 11-inch length are designed for durability and ongoing use with Stanley tools, making it appropriate for professional workshop tasks as well as home projects.
