Vented Screws - Hex Head

Em stock Em produção

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 hexagonal head. They are made from Stainless Steel.

  • Material: Stainless Steel
  • AISI 304, 1.4301
  • Strength Class: 70

Button Head Seal Screws

Em stock Em produção

Seal screws are a type of fastener designed with an o-ring to provide secure bi-directional protection against contaminates such as gases and fluids in various applications, minimising the risk of damage to sensitive equipment. They prevent the entry of water, dust, or other contaminants, ensuring a secure, reliable connection.

Seal screws are used in threaded and non-threaded holes in applications such as cabinets or used in the automotive and electric industries.

This range of Seal Screws features a button head with a hexagonal drive. Hexagonal drives are ideal for precision assembly and are used where less surface area is available. They are made from Stainless Steel that provides good resistance to corrosion and is slightly magnetic.

Please note: Our seal screws are designed for use in applications where sealing properties are required. It could be confused with standard fasteners, these do not require sealing properties and with an O-ring you will not get a sealing property like you get with seal screws and may damage the ring.

  • Material: Stainless Steel
  • AISI 303, 1.4305 or AISI 316, 1.440
  • Tensile strength: 550 N/mm² or 480N/mm²
