6.35mm [.250 in] Bit Torque Wrench, Pre-set to 4 in-lbs [0.45 Nm], for SSMA Brass

RN-RTW-ECO-6.35-4 Economical Torque Wrench | RF Connector Installation Tool

The RN-RTW-ECO-6.35-4 economical torque wrench is constructed with a durable tool steel spanner finished with nickel plating, ensuring excellent mechanical strength and corrosion resistance for long-term use. The handle is made from lightweight black anodized aluminum, providing ergonomic handling and stable control during connector installation. Featuring a 6.35 mm (1/4 inch) width across flats and a preset torque mechanism, this tool is designed to deliver consistent mechanical performance in RF assembly environments.

Designed for precise installation of RF connectors, the RN-RTW-ECO-6.35-4 torque wrench applies a fixed torque value of 4 lb-in (0.45 Nm), helping to prevent over-tightening or insufficient tightening that may degrade electrical performance. It is specifically suitable for SSMA connectors with brass construction and is widely used in RF cable assembly, laboratory testing, and production-line operations where repeatable and controlled torque application is required.
