Socket KS Tools 911.1040 400mm Chromium-vanadium steel

The KS Tools 911.1040 400mm Chromium-vanadium steel socket extension is a heavy-duty workshop accessory designed to extend reach and transfer torque reliably in demanding applications. Manufactured from chromium-vanadium steel, this 400 mm extension provides a solid connection between a drive tool and sockets, enabling access to recessed or hard-to-reach fasteners while maintaining torsional strength and durability.

Advantages

This socket extension offers robust mechanical strength and resistance to wear thanks to its chromium-vanadium steel construction. Its 400 mm length increases accessibility in deep engine bays and machinery housings. The precision-machined interfaces ensure a secure fit to minimize play and slipping during use, and the substantial mass contributes to stability when applying high torque.

Suitable for

• Automotive repair and maintenance where deep or recessed fasteners must be reached
• Industrial machinery service and assembly tasks with limited access
• Heavy-duty fastening and loosening operations requiring a long extension

Key specifications

• Material: chromium-vanadium steel for enhanced strength and wear resistance
• Length: 400 mm to extend reach to recessed fasteners
• Weight: 2.35 kg indicating a solid, durable build
• Finish: machined surface for accurate coupling and reduced play

How to use

Select a compatible drive tool and socket that match the intended fastener size. Firmly attach the socket to the extension and then connect the extension to the drive tool, ensuring the detent or locking mechanism engages where present. Guide the extension into position over the fastener, then apply torque using steady, controlled force. After use, inspect the extension for wear, clean off debris, and store in a dry tool chest to prevent corrosion.

Recommendations

Use with correctly rated drive tools and sockets, and avoid applying impact blows unless the extension and connected tools are specified for impact use. Regularly inspect for damage or excessive wear before each use and replace the extension if deformation or cracking is present.
