[✅ Features & Recommended Points]
●High Precision and Strength Design
Designed with a focus on diagonal dimension accuracy and drive socket stability, minimizing play in joint gaps. The structure maintains sufficient cross-sectional area, ensuring rigidity that reduces bending and deformation during use.
●“Power-Fit” Surface Contact Shape
Adopts a surface contact design (“Power-Fit” shape) at the drive socket area. This reduces concentrated stress on contact surfaces, efficiently transmits force, and minimizes wear on both the tool and the bit.
●Slim Shaft Design for Smooth Fast Turning
The center of the extension bar shaft is slimmed down, making rotation easier when a socket is attached (fast turning). Designed with consideration for operability in tight spaces.
●Applicable Drive Size = 6.35 mm (1/4 inch)
This product features a standard 6.35 mm (1/4 inch) drive, ideal for use with 1/4-inch drive sockets and bits. Highly versatile, it can be easily combined with your existing socket wrench or bit sets.
●Perfect 100 mm Extension Length
With a moderate length of 100 mm, it is convenient for situations requiring light extension, not overly long, and maintains strength—a well-balanced length design.
●Lightweight Design (approx. 48 g)
At 100 mm length, the mass is about 48 g (see specifications), offering easy handling and reducing strain on arms and wrists during long tasks.
●Domestic Quality and Trusted Brand
KTC (Kyoto Tool Company) is a highly trusted Japanese tool brand. With a commitment to design, material selection, machining accuracy, and finishing, it delivers consistent quality and is supported by users seeking durable tools.
●Note: Do Not Connect Multiple Bars
For safety and strength reasons, connecting multiple extension bars is prohibited. Always use a single bar.
[🔧 Ideal Use Cases]
- Tight spaces such as engine compartments or under chassis for fastening or loosening bolts and nuts.
- Maintenance and repair of home appliances or machinery where a socket wrench alone cannot reach deep areas.
- Use with a bit driver as a bit extension tool.
- Can be used with various sockets and bits, making it an ideal first extension tool for expanding your tool set.
