Kielder 3/8" Professional Torque Wrench (10 - 110Nm) – KWT-208-04

The Kielder 3/8" Professional Torque Wrench (10 - 110Nm) is a precision-calibrated tightening tool engineered for automotive workshops, motorsport service crews, and precision mechanical applications. Rated from 10Nm to 110Nm, every individual wrench is fully tested and supplied with an official certificate of calibration confirming compliance with DIN ISO 6789 and ASME B107.300-2010 standards.

Featuring a heat-treated steel ratchet head, a durable all-metal handle, and a quick-release locking collar, it guarantees long-term accuracy and fast, single-action torque adjustments. The positive-action "click" mechanism ensures reliable force application, while the compact 410mm length provides optimal manoeuvrability in confined service bays.

Why Choose the Kielder 3/8" Professional Torque Wrench?

A calibrated mid-range torque wrench is essential for:

• Tightening lower-to-mid range fasteners on engine components and suspension setups
• Motorsport service bays requiring certified precision in restrictive spaces
• Preventing over-tightening or fastener shear on sensitive automotive assemblies
• Long-term durability and resistance to calibration drift via a robust metal build
• Fast, secure torque adjustments using a quick-release lock collar

Unlike bulkier 1/2" variants, this 3/8" drive model delivers exact torque control for smaller fasteners without compromising professional-grade strength.

Frequently Asked Questions

What is the torque range of this wrench?

It is rated from 10Nm to 110Nm, making it ideal for lower-to-mid range automotive fasteners and engine components.

Does it come with a calibration certificate?

Yes. Every unit is tested and supplied with an official certificate of calibration to DIN ISO 6789 and ASME B107.300-2010 standards.

Can torque be applied in both directions?

No. Torque can only be applied in one direction (clockwise), though the head features a switchable direction function to easily back the tool out of tight spaces.

How do I know when the target torque is reached?

The wrench delivers a distinct positive-action "click" sound and feel when the set torque level is achieved.
