21 mm Torque Socket for Wheel Work

The Lock Technology 1500DD is a 21 mm torque socket rated to 100 ft.-lb. It is intended for technicians and vehicle owners who need a precise tightening tool for lug nuts on compatible wheels. The sky blue finish provides quick visual identification in a busy tool set. This new item ships directly from the manufacturer.

Socket Construction and Daily Use

The socket is built to withstand repeated torque applications at its rated limit. Its 21 mm drive size fits standard lug nuts requiring that specific dimension. The sky blue colour coding helps prevent mixing with other sockets during fast-paced wheel changes. Transparent elements in the construction allow visual confirmation of engagement.

Torque Limit and Compatibility Constraints

The 100 ft.-lb. rating defines the maximum torque this socket should transmit. Applying higher torque risks damaging the tool or the fastener. Buyers whose wheels require a different drive size or a higher torque specification cannot use this socket for those applications. The fixed 21 mm size also prevents use on nuts needing other dimensions.

Questions about this item

What torque value does the 21 mm Sky Blue socket limit to?

The socket is calibrated to 100 ft-lb so it stops tightening once that torque is reached.

What drive size does the 1500DD socket need to fit on?

It fits a standard 1/2 inch drive ratchet or breaker bar used for wheel nuts.

How do I install the 21 mm torque socket and what mistake should I avoid?

Slide it onto a 1/2 inch drive, seat it fully on the lug nut, and turn until it clicks; do not keep forcing it past the click.
