What is the recommended procedure for tightening nuts on transparent plastic enclosures?

The recommended procedure for tightening nuts on transparent plastic enclosures is to tighten them to a firm fit and then back off one full turn. This approach is important because transparent plastic materials can be particularly sensitive to stress and deformation. Over-tightening can lead to cracking or breaking of the plastic, as it does not have the same ability to flex or deform as metallic materials.

By tightening to a firm fit, the nuts create a secure connection without overwhelming the plastic structure. Backing off one full turn allows for some flexibility, which is crucial in preventing damage and maintaining the integrity of the enclosure, especially in environments where temperature changes might lead to expansion and contraction of materials. This method balances the need for security in fastening with the sensitivity of the enclosures to avoid damage.
