Vented Screws, also known as vacuum screws, are specially designed to release gases and pressure through the middle of the fastener. Vented screws are widely used within vacuum systems and enable faster, more efficient pump-down of HV, UHV, and EUV systems. These components allow the quick evacuation of trapped pockets of air and surface contaminants from blind-tapped holes.
A vented screw is designed for use in applications where trapped bubbles of air can cause problems - for example, in glove boxes and clean rooms. The vent allows trapped air and trapped gases under the screw to be released quickly. Therefore, systems that are subjected to vacuum conditions can reach low pressures more quickly - and indeed remain at low pressures more effectively. They provide complete evacuation of trapped volumes of air during pump-down and eliminate virtual leaks.
Our range of vented cap head screws are a robust and reliable option when used in applications where there is a high risk of the fastener coming into contact with fluids. They features a central vent which removes condensation and reduces chattering. The screws feature a cap head with an hexagonal drive ideal for precision assembly, this can be useful when less surface area is available on both materials and in tight spaces.
Vented screws are fasteners with a hole drilled through the middle that allow gases trapped at the bottom of a blind threaded hole to escape through the core and provide airflow within an application. The screws are a common option for HV and UHV systems because their centre vent feature reduces virtual leakage from high vacuum systems.
This range of Vented Screws features a countersunk machine head with a hexagonal drive. Hexagonal drives are suitable for precision assembling and when there is limited surface area. They are made from Stainless Steel.

The screws hollow core acts like a venting system. The range complies to DIN 912 (with central vent). They are made from ultrasonically cleaned austenitic Stainless Steel that provides very good resistance to corrosion, good strength and machinability.
The material is a popular choice for construction and automotive applications.
