X10 (NEX10™), 4.3-10, 7/16, N-type, 2.2-5 and SMA Torque Wrenches

. Published on

Hughes break-over torque wrenches are designed to minimise impairment to connections by ensuring accurate mating forces are delivered to transition points when mating RF coaxial connectors.

The unique break-over feature triggers free movement through a 10-degree non-torqueing arc, at the axis of the tool movement to indicate to that desired torque has been reached and assure users of a first-class connection free of over-torque damage.
