The Norbar 13851 is designed for controlled tightening of small fasteners where excessive torque can damage housings, strip threads or compromise delicate components. Its adjustable range of 0.6–3 N·m makes it suitable for panel assembly, instrument manufacturing and other precision fastening applications.

The slipping mechanism operates when the preset torque is reached, helping reduce the risk of over-tightening. Torque settings can be adjusted without specialist tools, while the locking feature helps prevent accidental changes during operation.

The screwdriver features a 1/4" hexagon bit holder with a 4 mm hexagon stem and accepts standard 1/4" bits. Its bi-material handle combines a strong base with a soft, slip-resistant grip to support comfortable handling during extended use. The tool conforms to ISO 6789 and is designed to maintain accuracy over many thousands of tightening cycles.

For interim checking, the Norbar TST 2 Series 2 and TST 25 Series 2 bench testers are suitable options. ISO 6789-1:2017 recommends recalibration after 12 months or 5,000 cycles, whichever comes first, or sooner following a drop or overload.

When choosing a torque screwdriver, select a range that places your most frequently used torque setting comfortably within the scale. For a higher torque range, consider the Norbar 13852, which covers 1.2–6 N·m.
