Buying Considerations
When selecting the Stanley Combination Wrench 7mm 85-587, consider these critical factors:
Application Requirements: This wrench excels in automotive repair, machinery maintenance, and assembly line applications where 7mm fasteners are common. Verify your specific fastener sizes before purchasing.
Access Constraints: The long strong type design provides superior reach for deep-set fasteners. Measure your workspace clearance to ensure the 120mm length fits your application.
Torque Needs: With a maximum torque capacity of 45 Nm, this wrench handles most industrial applications. For higher torque requirements, consider torque wrenches or impact tools.
Material Compatibility: The chrome vanadium steel construction resists corrosion and wear, making it suitable for harsh industrial environments. For specialized applications, explore specialty wrenches with different material properties.
Set vs Individual: While this 7mm wrench addresses specific needs, consider purchasing a complete combination wrench set for comprehensive coverage across multiple fastener sizes.
Frequently Asked Questions
Q: What is the advantage of the "Long Strong Type" design?
A: The Long Strong Type provides extended reach for accessing deep-set fasteners and increased leverage for applying higher torque. The extended handle length allows for better force application while maintaining the same head size for tight spaces.
Q: Can this wrench be used with impact tools?
A: No, the Stanley 85-587 combination wrench is designed for manual use only. Using it with impact tools may damage the wrench and void the warranty. For impact applications, consider impact sockets specifically designed for such use.
