Performance Features
This wrench features a 12-point box end design that allows for 30° swing access in confined spaces, making it ideal for automotive engine compartments and machinery with limited clearance. The open end is chamfered for easy fastener engagement, while the box end provides maximum contact surface for high-torque applications. The long handle design increases leverage by approximately 40% compared to standard wrenches, enabling technicians to apply greater force with reduced effort.
Buying Considerations
When selecting combination wrenches for professional use, several factors are critical:
Size Range Requirements: Consider purchasing the Stanley 7mm wrench as part of a comprehensive metric wrench set to ensure you have the right size for various applications.
Material Quality: The Chrome Vanadium steel construction provides superior strength and durability compared to standard carbon steel tools. This material choice ensures the wrench can withstand repeated use without deformation.
Handle Length: The Long Strong Type handle offers enhanced leverage but requires consideration of workspace clearance. For extremely confined spaces, standard length wrenches might be more appropriate.
Surface Finish: The fine polished chrome finish not only provides corrosion resistance but also reduces friction during use, making fastener removal easier.
Application Environment: This wrench is ideal for automotive repair, industrial machinery maintenance, and equipment assembly where precise torque application in confined spaces is required.
Frequently Asked Questions
Q: What is the advantage of the Long Strong Type handle design?
A: The extended handle provides approximately 40% more leverage than standard wrenches, allowing for greater torque application with less physical effort. This is particularly beneficial for stubborn or corroded fasteners that require significant force to loosen.
Q: Can this wrench be used with impact tools?
A: No, the Stanley 85-587 is designed for manual use only. Using it with impact tools or cheater bars can damage the wrench and potentially cause injury. For impact applications, consider dedicated impact sockets and tools.
Q: How does the 12-point box end compare to 6-point designs?
A: The 12-point design allows for 30° swing access in confined spaces, making it ideal for tight working conditions. However, 6-point wrenches provide better grip on fasteners and are less likely to round off corners, making them preferable for extremely tight or damaged fasteners.
