1. A latch assembly apparatus, comprising:
an effort arm;
a latch housing, comprising:
a resistance arm comprising a claw portion; and
an ejection arm;
a fulcrum; and
a torsion spring configured to provide a rotational force around the fulcrum, and on the resistance arm, resulting from a tensioning of the torsion spring between a first end of the torsion spring fixed to the effort arm, and a second end of the torsion spring fixed to a predetermined preload gradient hole disposed on the latch housing, wherein when the latch assembly apparatus is mounted to a removable element, and the removable element is placed in a connection with a drawer element by the latch assembly apparatus, the resistance arm applies a preload to the connection via the torsion spring.
