Vented Countersunk Machine Screws

In production

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.

  • Their centre vent feature reduces virtual leakage from high vacuum systems.
  • Ideally suited for usage in sealed enclosures, housings, and machinery.
  • Hexagonal drives are suitable for precision assembling.
Material: 316 Stainless Steel, 304 Stainless Steel Series Code: SRP0093.A4
