Our vented socket screws are available in various sizes and configurations to meet diverse project requirements. Review our detailed dimensioning and specifications tables below to find the appropriate vented socket screw for your application. We also accept custom requests for tasks that require nonstandard sizes, coatings and configurations.
Vented screws, also referred to as vacuum vented screws, are a type of fastener designed with a vented hole running along its axis. The purpose of the vent is to release gases or built-up pressure once the fastener is tightened and the system becomes closed. These screws improve system efficiency by minimizing virtual leaks, accelerating pump-down times and maintaining system integrity.

Industries & Applications
Vented hex screws made from exotic alloys are invaluable across various industries that require precise pressure regulation, moisture regulation and improved airflow.
High and ultra-high vacuum systems in chemical industries employ vented screws in 316L stainless, Titanium, and Inconel 625 to minimize virtual leaks, withstand bake-out temperatures, and maintain vacuum integrity under thermal stress.
Aerospace Systems
Aircraft and spacecraft components, such as avionics bays, environmental control systems and access panels, rely on vented screws in Titanium, Inconel, A286, and Hastelloy to handle extreme conditions like vibration, temperature swings, and high-stress loads while maintaining gas venting properties.
Medical and Laboratory Equipment
Biocompatible and sterilization-resistant vented screws in medical and laboratory equipment are typically made from Titanium (Grade 2 or 5) and 316L stainless steel, ensuring resistance to corrosion, autoclaving, and chemical exposure in clean environments. You can find these screws in equipment such as patient monitoring devices, diagnostic imaging equipment and respiratory and ventilation devices.
Clean Room Assemblies
Cleanroom applications favor 316L stainless steel, Titanium, and occasionally Aluminum alloys (for weight-sensitive systems) to maintain ultra-low particle emission and resist aggressive cleaning agents and protocols.
Tips for Purchasing Vented Socket Screws
For the best project outcome, keep the following factors in mind when selecting vented socket screws:
Material selection: Choose materials based on your application’s environmental demands and performance criteria. Check for factors such as temperature, corrosion and pressure levels.
Dimensions: Review key dimensions, including the nominal diameter, thread pitch and vent dimensions, using our detailed specifications table. Ensure the screw’s thread matches your application’s requirements for secure fastening and proper gas venting.
Head style: Select the appropriate head type based on space constraints, aesthetics and torque application needs.
Vacuum requirements: Ensure the screw’s venting capabilities align with your vacuum or pressure requirements.
Custom options: Inquire about nonstandard sizes, finishes or configurations that may optimize your design.
