Keysight / Agilent / HP 8710-1766 Torque Wrench

The Keysight/Agilent/HP 8710-1766 is a break-over click-type torque wrench engineered for precision tightening of RF coaxial connectors. It applies a fixed torque of 135 N-cm (12 in-lb) to prevent both over-tightening—which damages connector contacts and dielectric—and under-tightening, which degrades signal integrity. The tool’s steel head and anodized aluminum handle deliver reliable, repeatable torque delivery across production and maintenance workflows in RF and microwave system assembly.

## Technical Specifications

## Key Features

• Fixed torque setting eliminates guesswork during connector mating
• Click-type break-over design provides tactile feedback at the preset torque value
• Compact 166 mm length and 93.2 g weight enable one-handed operation in tight panel spaces
• 3/4 inch wrench flats accommodate open-ended wrenches to prevent connector rotation during mating
• Steel head withstands repeated use in high-volume production environments

## Typical Applications

• 7 mm and Type-N RF connector assembly and maintenance
• Laboratory and field calibration of RF test fixtures
• Production rework and connector replacement in microwave systems
• Field service where connector repeatability is critical to system performance

## Compatibility & Integration

The 8710-1766 integrates with the HP/Agilent/Keysight 19 mm torque wrench ecosystem. Pairs with the 8710-1770 open-ended wrench (1/2″ and 9/16″ sizes) to restrain connector body rotation during torque application.
