Open-End and Box Wrench GEKO T00626 satin finish, Cr-V steel, 26 mm, DIN 3113A

GEKO open-end and box wrench T00626 is a 26 mm combined hand tool made from chromium-vanadium (Cr-V) steel with a satin finish and manufactured to DIN 3113A dimensional and strength standards. The tool pairs an open-end jaw on one side with a boxed ring on the other, offering a single, compact wrench that covers both immediate turning and fully enclosed gripping of hex fasteners. The satin finish improves surface durability and reduces glare while preserving the tool’s industrial appearance.

Advantages

The GEKO 26 mm combined wrench provides a balance of strength and precision due to its Cr-V steel construction and compliance with DIN 3113A. The double-ended design reduces the need to carry multiple sizes by combining an accessible open jaw with a secure box end in one tool. The satin finish resists corrosion and hides minor wear, and the standardized dimensions ensure compatibility with metric nuts and bolts commonly used in maintenance, automotive and industrial applications.

Suitable for

• Tightening and loosening 26 mm metric nuts and bolts
• Automotive repair and service work
• General machinery and equipment maintenance
• Industrial assembly and light fabrication tasks

Key specifications

• Tool type: Combined open-end and box wrench
• Working size: 26 mm
• Material: Chromium-vanadium (Cr-V) steel
• Finish: Satin
• Standard: Manufactured to DIN 3113A dimensional and mechanical requirements

How to use

Select the 26 mm wrench end that best fits the fastener and position the tool square to the flat faces of the nut or bolt head. Use the open-end side for quick placement in tight spaces or where entry from the side is required; use the box end for greater contact area and reduced rounding when applying higher torque. Apply steady, controlled force and avoid sudden impacts. Inspect the wrench before use for signs of wear or damage and replace if deformation or cracks are present.

Usage recommendations

For accurate and safe operation, use the box end for final tightening to minimize fastener rounding and reserve the open end for positioning and clearance work. Store the wrench in a dry tool organizer to maintain the satin finish and prevent corrosion. Do not use the wrench with cheater bars or as a hammer; adhere to recommended torque limits for fasteners to avoid tool or fastener damage.
