Shaft adapter 4-96065-ETA

DINcompactquick-change

The 4-96065-ETA torque adapter is a preset, click-type torque adapter designed to convert a 1/4 inch bit and holder into a precise manual torque tool that prevents overtightening. It emits an audible click when the preset torque is reached and is suitable for demanding applications where repeatable torque is required.

Key features

• Preset torque, precise for at least 20,000 clicks
• Tolerance ±10% (factory certificate available on request)
• Tightening torque: 6.5 Nm / 66.2 Kgf·cm / 57.5 in·lbf
• Bit magnetic holder: 1/4 inch hexagon (6.35 mm) — DIN 3126
• Drive: 1/4 inch hex shank — DIN 3126
• Material: alloyed steel
• Adapter diameter: 20 mm
• Adapter length (without shank): 33.5 mm
• Total length: 43.5 mm
• Weight: 69 g

Area of application
Convert a 1/4 inch bit and a holder into a reliable torque tool. The torque value is preset in the adapter and can be clamped between any standard holding tool and a bit. An audible click indicates when the torque is reached and prevents overtightening. The adapter does not unlock during loosening (due to the blocked core shaft), so no additional release tool is required and loosening torque is approximately 30% higher. The adapter is primarily intended for manual operation.

Technical description
The adapters are tested according to DIN EN ISO 6789 (manually operated torque screwdriving tools) and guarantee a tolerance of ±10% for at least 20,000 clicks. Users should periodically check the torque value with a torque meter. The adapter locks the ratchet inside the bushing sleeve: a hollow core shaft and a damping cylinder interact so that when applied torque exceeds the preset value the core shaft becomes inactive and further torque is not transmitted to the fastener.

General information
Torque adapters provide a compact solution for electronics assembly, quick-change systems, robotic stations, aerospace, medical equipment or general workbenches where repeatable, preset torque is required.
