The TW-S SMA-Type Torque Wrench is a proof-coupling torque wrench for small coaxial connectors — including SMA, 3.5 mm, 2.92 mm, 2.4 mm, and 1.85 mm types. It ensures proper, repeatable torque when mating or disassembling these connectors, preventing over-tightening or inadequate tightening which can degrade RF performance or damage connectors.
