The Keysight/Agilent/HP 8710-1764 is a precision torque wrench engineered for controlled fastening of RF connectors and critical assemblies. It delivers exact torque application to prevent over-tightening damage while maintaining proper connection integrity and signal performance. The open-ended wrench design engages connector body flats to restrict rotation during coupling nut tightening, making it indispensable for RF/microwave systems and precision electronic assembly.
## Technical Specifications
• Torque Setting: 8 lb-in (0.90 N·m)
• Coupling Torque: 90 N·cm
• Coupling Nut Wrench Flat Width: 20 mm
• Design: Open-ended wrench configuration
• Manufacturer: Keysight Technologies (formerly Agilent Technologies, formerly Hewlett-Packard)
• Model: 8710-1764
• Product Family: 8710 Series Torque Wrenches
## Key Features
• Fixed torque setting of 8 lb-in (0.90 N·m) for RF connector applications
• Wrench flats specifically designed to engage outer connector bodies
• Prevents relative rotation between mating connectors during assembly
• Supports dual-wrench technique—one wrench on connector body, torque wrench on coupling nut
## Typical Applications
• Type N connector assembly (50 ohm and 75 ohm variants)
• 3.5 mm connector fastening (standard, NMD, male test ports)
• 2.4 mm connector assembly (standard, NMD, male, female NMD variants)
• RF and microwave system calibration and maintenance
• Electronic component assembly requiring precise torque control
## Compatibility & Integration
The 8710-1764 is explicitly designed for Type N, 3.5 mm, and 2.4 mm RF connectors commonly found in test, measurement, and communication equipment. The 8 lb-in (0.90 N·m) torque specification is critical for maintaining mechanical and electrical integrity in precision RF connectors, particularly 3.5 mm male test ports and 2.4 mm male connector variants. The tool integrates into standard RF assembly workflows where connector body restraint and controlled coupling nut torque are both required.
