The Norbar 13850 is designed for low-torque fastening applications where small screws and delicate components require careful tightening. With a torque range of 0.3–1.5 N·m, it is suitable for electronics, optical equipment, medical devices and precision instrument assembly.

Its slipping mechanism operates when the preset torque is reached, helping reduce the risk of over-tightening and damage to small fasteners. The torque setting can be adjusted without specialist tools, while a 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 for improved comfort during extended use. The tool conforms to ISO 6789 and is designed to maintain its 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 selecting a torque screwdriver, choose a range that places your most frequently used torque setting comfortably within the scale. For a higher range, consider the Norbar 13851, which covers 0.6–3 N·m.
