Llave dinamométrica Bahco 74WR-50

The Bahco 74WR-50 torque wrench is a precision hand tool engineered for accurate torque application in automotive and mechanical work. It combines a robust steel construction with a reversible ratchet head and an easy-to-read scale to deliver repeatable tightening results. The wrench is calibrated to provide dependable torque values and features an ergonomically shaped handle for sustained use.

Advantages

The tool offers precise torque control through a clear scale and a reliable adjustment mechanism, reducing the risk of over- or under-tightening. Its reversible ratchet head enables fast bolt engagement and convenient direction changes without removing the tool from the fastener. Durable materials and careful calibration ensure consistent performance and long service life under workshop conditions.

Suitable for

• Automotive engine and chassis fastener tightening
• Mechanical assembly and maintenance tasks
• Bicycle and light vehicle servicing
• Industrial equipment assembly where controlled torque is required

Key specifications

• Torque range: suitable for medium-range torque applications (specified model designed for a defined torque span)
• Drive size: reversible ratchet head compatible with standard sockets
• Scale: clear, easy-to-read torque scale for setting target torque
• Construction: robust steel body for workshop durability
• Handle: ergonomic grip for comfortable use during repeated operations

How to use

Select the appropriate socket and fit it to the drive of the torque wrench. Set the desired torque value using the adjustment mechanism while observing the scale. Position the wrench squarely on the fastener and apply steady force in the intended rotation direction until the wrench indicates the target torque. For reversing direction, use the reversible ratchet head rather than rotating the tool body. After use, return the adjustment setting to the wrench's lower limit to relieve internal spring tension and store the tool in a dry place.

Recommendations

Regularly verify calibration according to the frequency required by your workshop practices or manufacturer recommendations. Clean the torque wrench after use, avoid impacts or dropping, and do not use it as a breaker bar. Use sockets and fasteners in good condition to ensure accurate readings and consistent performance.
