FAQ
Q1: What is a single open-end wrench?
A1: A single open-end wrench has one fixed open jaw and a handle. It is mainly used to tighten or loosen matching hex nuts and bolts from the side.
Q2: What size range is available?
A2: This series covers large sizes from 24mm to 85mm. Choose the wrench according to the across-flats dimension of the nut or bolt.
Q3: What are the advantages of phosphate treatment?
A3: Phosphate treatment improves surface rust resistance, corrosion protection, and wear durability, making the tool suitable for general industrial and construction environments.
Q4: Can it be used for pipelines and valves?
A4: Yes. Large single open-end wrenches are suitable for pipe connections, valve nuts, flange fasteners, and other oversized hex components.
Q5: Is it suitable for high-torque applications?
A5: It is suitable for normal industrial installation, maintenance, and fastening work. For severely rusted, seized, or extremely high-torque fasteners, use penetrating oil and appropriate torque tools such as breaker bars or hydraulic wrenches, while avoiding overload.
Q6: How do I choose the correct size?
A6: Measure the distance across the two parallel flats of the nut or bolt head, then select the matching wrench size. For example, use a 50mm wrench for a fastener with a 50mm across-flats dimension.
Q7: Do you support customization?
A7: Yes. OEM/ODM customization is available for logos, jaw sizes, lengths, surface finishes, packaging, and wrench set configurations.
