Chiave a stella Gedore 6090640

The Gedore 6090640 combination wrench is manufactured from chrome-plated Gedore vanadium steel (31CrV3) and conforms to DIN 3113 Form A, ISO 3318 and ISO 7738 standards. The ring end is offset 15° from the shaft and the shaft is produced in a girder pattern. Sizes 3 to 5.5 are supplied with a hexagon ring and sizes 6 and above use a UD profile. A noted feature marked with an asterisk is not standardised.

Advantages

This combination wrench offers a standardized form factor for compatibility with metric fasteners, corrosion resistance due to chrome plating, and high strength from 31CrV3 vanadium steel. The 15° ring offset improves access in confined spaces and the girder-pattern shaft increases stiffness while keeping weight low. Available ring profiles by size ensure proper engagement with fastener heads.

Key specifications

How to use

Select the correct wrench size that matches the fastener. Position the open end or ring end on the fastener and apply steady force; the 15° offset helps reach fasteners in tight spots. Use the hexagon ring on sizes 3–5.5 or the UD profile on larger sizes to ensure full engagement. Avoid using the tool as a hammer or prying device to prevent damage to the wrench and the fastener.

Recommendations

Keep the chrome-plated surface clean and dry after use to minimize corrosion. Inspect the wrench regularly for wear or rounding on contacting faces and replace if damage impairs safe engagement. For torque-critical applications use a calibrated torque tool; this combination wrench is intended for manual fastening and general mechanical work.
