Κλειδί ροπής Beta BE666/20 υποδοχή 1/2 ίντσες 40–200 Nm, μήκος 47 cm

The Beta BE666/20 is a professional 1/2" drive torque wrench with an adjustable torque range of 40–200 Nm and a total length of 47 cm. It is engineered for controlled tightening of bolts and nuts in automotive, industrial and general maintenance environments. The tool features a clear, graduated scale for setting and verifying torque values, a robust steel construction for workshop durability and a mechanism designed to reduce the risk of over‑ or under‑tightening by delivering consistent torque application.

Advantages

This torque wrench provides precise torque control across a wide useful range, enabling accurate clamping and repeatable results. Its 1/2" drive accommodates commonly used sockets and accessories, while the 47 cm length offers appropriate leverage for the specified torque range. The graduated scale is easy to read for quick adjustments, and the durable construction withstands frequent workshop use. The ratchet head and adjustment mechanism are designed for stable operation and prolonged service life.

Suitable for

• Automotive wheel and engine component tightening
• Industrial assembly and machinery maintenance
• General workshop and maintenance tasks requiring controlled torque
• Installation and servicing of fastened joints where specification-based torque is required

Key specifications

• Drive size: 1/2" compatible with standard sockets
• Torque range: 40–200 Nm for medium to high torque applications
• Length: 47 cm for leverage appropriate to the torque range
• Scale type: graduated, adjustable setting for repeatable torque values
• Construction: hardened steel body and mechanism suited for workshop environments
• Head type: ratchet-style head for convenient socket operation

How to use

Select the required torque value on the graduated scale and lock the setting if applicable. Fit a suitable 1/2" socket to the drive, position the torque wrench on the fastener and apply force steadily until the wrench indicates the set torque (audible click or mechanical release, depending on the mechanism). Avoid sudden impacts or use as a breaker bar. After use, return the setting to the wrench's lowest value for storage to maintain calibration and mechanism life.

Recommendations

To preserve accuracy, have the torque wrench calibrated periodically according to usage frequency and store it in a dry place away from heavy impacts. Use the correct socket size and avoid extensions that change effective leverage unless you recalculate the resulting torque. Follow fastener manufacturer torque specifications when tightening critical joints.
