The Norbar 13902 TTi Non-Magnetic Adjustable Mechanical Torque Wrench, 3/8” Square Drive is engineered for precision fastening in applications where magnetic interference must be minimized. With a very low magnetic signature (relative permeability r ? 1.15), its ideal for sensitive assemblies while still delivering the rugged performance expected from a professional mechanical torque wrench. Its durable, reliable, and accurate mechanism provides consistent results, and the clear micrometer scale enables simple, error-free setting (on dual-scale models, micrometer increments apply to the Nm scale). Adjustment across the full range is quick and fingertip-lighttypically achievable in around ten turnshelping reduce setup time in multi-task workflows.

A comfortable two-material handle combines a strong structural core with a soft-feel, slip-resistant grip for improved control and reduced fatigue. The handle material and scale lens resist chemicals commonly encountered in automotive, aviation, and industrial environments. The Norbar 13902 TTi Non-Magnetic Adjustable Mechanical Torque Wrench, 3/8” Square Drives proven click system provides both tactile and audible indication at the target torque, while an integrated lock prevents accidental changes to the setting. A push-through ratchet supports both clockwise and counter-clockwise operation, and the handle includes a marked center/calibration force point to promote correct technique. Accurate to 3% and compliant with ISO 6789-1:2017, it is supplied with a Declaration of Conformance and is made in the UK.

The Norbar 13902 TTi Non-Magnetic Adjustable Mechanical Torque Wrench, 3/8” Square Drive is ideal for aerospace, defense, instrumentation, and precision manufacturing environments where low magnetism and repeatable torque control are essentialsupporting reliable tightening on benches, production lines, and field service work without compromising sensitive components.
