Κλειδί ροπής Bahco 74WR-15 15-75 Nm ρυθμιζόμενο καστάνιας

The Bahco 74WR-15 15-75 Nm Adjustable Ratchet torque wrench is a precision hand tool for applying controlled torque to fasteners. Engineered for repeatable accuracy across a 15–75 Nm range, this wrench combines an adjustable torque setting with a ratchet head to simplify tightening and loosening operations. The construction uses durable materials and a calibrated mechanism to support consistent torque delivery for workshop and field tasks.

Advantages

The adjustable torque range covers a wide span of medium-torque applications, allowing one tool to replace several fixed-value wrenches. The ratchet mechanism enables continuous operation without removing the wrench from the fastener, improving work speed and convenience. The calibrated scale and secure locking mechanism reduce the risk of torque drift during use, while robust construction increases resistance to wear and supports long-term reliability.

Suitable for (tasks / use cases)

• Automotive maintenance and component assembly requiring 15–75 Nm torque control
• Bicycle and light machinery repairs where precise torque is necessary
• Workshop assembly tasks and mechanical servicing of medium-sized fasteners
• Field service and maintenance jobs that require a portable, adjustable torque tool

Key specifications

• Adjustable torque range: 15–75 Nm
• Drive type: ratchet head for reversible operation
• Torque adjustment: calibrated scale with locking mechanism
• Intended use: hand-operated torque application for bolts and nuts
• Construction: durable metal body designed for workshop and field use

How to use

Select the required torque value on the calibrated scale and secure the setting with the locking mechanism before applying the wrench to a fastener. Position the ratchet head on the fastener and apply steady force until the wrench indicates the set torque. Use controlled motion and avoid sudden impacts; if reversing direction is necessary, switch the ratchet direction according to the head control. After use, release the lock and return the setting to a low value for storage to help preserve the calibration.

Recommendations

For accurate results, periodically check calibration and avoid using the wrench as a breaker bar or for applications above the specified 75 Nm limit. Clean and lightly lubricate the ratchet mechanism as needed, and store the tool in a dry place to maintain performance and longevity.
