The document discusses tools for accurately tightening SMA connectors, which is important for high frequency RF cabling applications. TB break-over wrenches and hand torque screwdrivers can tighten SMA connectors to the specified torque values without overtightening. Crowsfoot spanner heads are available in various sizes to work with hand torque screwdrivers for tightening connectors in hard to reach places. Ratcheting adapters can also be used to control tightening when used with torque wrenches.

1. Accessories Torque Wrenches
SMA CONNECTOR TOOLS
The correct tightening of SMA Connectors used in RF cabling applications
is essential to ensure optimum performance. This is particularly important in
high frequency applications using stainless steel or beryllium-copper bodies.
A torque value of around 1 N.m is generally being specified by connector
manufacturers for the tightening of precision connectors and around 0.5 N.m
for brass bodied connectors.
TB Break-Over wrenches & Hand Torque Screwdrivers are tools available to
accurately tighten SMA connectors and to ensure that over tightening cannot
occur. The TB is commonly used with an open ended spanner (usually
8mm), while the pre-set Minor Screwdriver with a Crowsfoot Spanner Head
enables vertical access in places where conventional torque tools cannot be
used. Spanners are available to suit the A/F sizes of all the major connector
manufacturers.
Other sizes and lengths available upon request.
