The Norbar TTi Non-Magnetic Adjustable Mechanical Torque Wrench 3/8” Square Drive 130503 is engineered for precision torque control in applications where magnetic signature matters. With a very low magnetic signature (relative permeability r ? 1.15), the Norbar TTi Non-Magnetic Adjustable Mechanical Torque Wrench 3/8” Square Drive 130503 ideal for sensitive environments while still delivering the rugged reliability expected from a professional mechanical torque wrench. The durable internal mechanism and proven click system provide clear tactile and audible indication when the target torque is reached, helping prevent over-tightening and improving repeatability.

Torque setting is fast and error-resistant thanks to the micrometer scale (micrometer increments apply to the Nm scale on dual-scale versions). Adjustment across the full range can be completed with minimal effort in approximately ten turns, and a positive locking feature prevents accidental changes once set. A two-material handle combines a strong structural base with a soft-feel, slip-resistant grip for comfort during repetitive work. The handle materials and lens are resistant to chemicals commonly encountered in automotive, aviation, and industrial environments. The push-through ratchet supports both clockwise and counter-clockwise operation, and the handle includes a marked center/calibration force point to encourage 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 TTi Non-Magnetic Adjustable Mechanical Torque Wrench 3/8” Square Drive 130503 is ideal for aerospace, defense, instrumentation, and precision manufacturing settings where low magnetism is required alongside reliable torque controlsupporting assembly, maintenance, and QA-driven fastening on benches, production lines, and field service work.
