Vent screw bolts are known for their unique capability of allowing opposite pressure balance. Vent screw bolts ensure a reasonably gaseous environment in devices or enclosures that must be kept sealed (non-emission) against the outside. In case differential pressure with respect to outside of the enclosure occurs, which is caused by temperature change or high altitude application, vent screw has channels in which air or gases can pass through, hence internal pressure build up is avoided. Such property is useful in outdoor items, aerospace parts and industrial machines with the need to control pressure for safety & function.

This refers to the accumulation of pressure inside a sealed volume that may arise from heat transfer, chemical reactions or mechanical processes occurring in the sealed chamber. Excessive internal pressure can distort or rupture sealed container or system components, damaging the enclosure, and/or causing system demise. Vscrew bolts are used to vent unused air, where this will help prevent system overpressure and maintaining safe reliable operation.

The focus of vent screw bolts is also on the airflow and ventilation within a system, component or enclosure. They enable the fresh air to flow while lot of stale or dirty air is dispersed. When employed strategically, vent screw bolts form channels that allow air to pass through and aid in moving heat away from components like processors, power electronics or engines. It protects the device from heating, it stops overheating, which can reduce performance or fail components. Vent screw bolts improve the efficiency of mechanical or electronic devices by providing cooling.
