Wrench (open-ring) Topex 30 mm model 35D395

The Topex open-ring (combination) wrench 30 mm, model 35D395, is a hand tool designed for tightening and loosening hexagonal nuts and bolts of matching size. One end features an open jaw for quick engagement and handling in confined spaces, while the ring end provides full 12-point contact for secure torque transfer and reduced rounding of fasteners. Constructed for routine mechanical repairs, assembly work and maintenance tasks, the wrench balances accessibility and leverage for professional and DIY use.

Advantages

The open-ring design combines fast access with reliable grip: the open jaw allows swift placement on fasteners, while the ring end ensures even force distribution. The 30 mm size offers compatibility with medium-to-large fasteners commonly found in automotive, machinery and structural applications. Its solid construction provides durability under frequent use, and the slim profile helps reach bolts in tighter locations where bulkier tools cannot.

Suitable for

• Automotive maintenance and repair (engine and chassis fasteners)
• Assembly and disassembly of industrial machinery
• Workshop and garage general maintenance tasks
• On-site installation and service work requiring portable hand tools

Key specifications

• Wrench type: open-ring (combination) wrench
• Size: 30 mm across flats
• Ends: open jaw on one end, ring (box) end on the other
• Contact style at ring end: multi-point seating for secure torque transfer
• Typical applications: nuts and bolts with 30 mm hex heads

How to use

Select the 30 mm end appropriate for the fastener. Position the open jaw for quick access or the ring end for a more secure grip when higher torque is required. Apply steady force in the intended rotation direction, keeping hands clear of pinch points. For stubborn fasteners, ensure correct seating of the ring end to avoid rounding; avoid using the wrench with excessive impact or as a hammer. Store the tool in a dry place after cleaning to maintain performance.

Usage recommendations

For safe and effective use, pair the wrench with appropriate personal protective equipment and use the ring end when higher torque and secure contact are necessary. Inspect the fastener engagement before applying full force and avoid extensions or cheater bars that can overload the tool.
