Extension bar Knipex 98 45 125 — chrome vanadium steel, 1 pc

The Knipex 98 45 125 extension bar is a single-piece tool designed to increase reach when working with sockets and wrenches. Manufactured from forged chrome vanadium steel, this extension bar provides a straight, solid connection between drive tools and sockets to access fasteners in recessed or confined areas. It is supplied as one piece and is compatible with square-drive socket systems where an extended reach is required for mechanical or maintenance tasks.

Advantages

The extension bar's forged chrome vanadium steel construction offers durability and wear resistance for repeated use. Its internal and external square features allow secure engagement with both tools and sockets, while the quick-locking mechanism ensures reliable retention of attached sockets during torque application. The single-piece design minimizes play and maximizes transfer of torque for stable operation in professional and DIY settings.

Suitable for

• Reaching recessed bolts and nuts in engines and machinery
• Automotive maintenance and repair tasks
• Assembly and disassembly in tight spaces
• General mechanical and workshop applications

Key specifications

• Material: forged chrome vanadium steel
• Design: single-piece extension bar
• Drive type: internal and external square drive interfaces
• Connection: quick, reliable locking of sockets
• Quantity: 1 piece

How to use

Select a socket that matches the fastener size and attach it to the external square of the extension bar until it locks. Connect the internal square to the corresponding drive tool such as a ratchet or wrench. Position the socket on the fastener, then apply torque through the drive tool while maintaining alignment. After use, depress any release mechanism if present and remove the socket. Store the extension bar in a dry tool storage area to maintain condition.

Usage recommendations

Use the extension bar with compatible square-drive sockets and tools rated for the required torque. Avoid excessive bending loads or using the bar as a lever beyond its intended design. Keep contact surfaces clean and inspect for wear or damage before use to ensure safe and reliable operation.
