Vented Countersunk Machine Screws

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

Vented Screws - Cap Head

This range of Vented Screws features a cap head with a hexagonal drive. Hexagonal drives are ideal for precision assembly and are ideally used where less surface area is available.

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.

  • Hollow core provides an integrated vent system.
  • Made from ultrasonically cleaned austenitic Stainless Steel that provides good resistance to corrosion.
  • Complies to DIN 912.

Vented Shoulder Screws - Cap Head

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 Shoulder Screws features a cap head with a hexagonal drive. Hexagonal drives are suitable for precision assembling and when there is limited surface area and the precision shoulder allows accurate assembly. They are made from Stainless Steel.

  • The shoulder feature of these screws provides additional surface area for improved grip.
  • Vented design allows for controlled airflow, making them ideal for applications where proper ventilation is crucial.
  • Suited for sealed enclosures, housings, and machinery.
