Fixed Click-Type Torque Wrench with 5/16" Bit Precision RF/Microwave Connector Torque System Prevent the over-tightening of expensive RF components with this professional-grade, factory-preset click-type torque wrench. Equipped with a 5/16" hex open-end bit, it is optimized for SMA, 1.85mm, 2.4mm, 2.92mm, and 3.5mm connectors. The break-over mechanism provides a distinct tactile and audible "click" when the preset torque limit is reached, ensuring highly repeatable, low-VSWR connections. Constructed from hardened chrome vanadium or stainless steel, this wrench comes factory-certified and serialized for laboratory tracing.
