untightened

Left slightly slack

Untightened describes something that has not been made tight, or that has been loosened from a tight state.

A screw left untightened may work its way out.

The untightened bolts rattled as the engine ran.

The word appears most often in mechanical and technical contexts where proper tightening matters for safety or function.
