Button Head Seal Screws

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..

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. 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.

  • Designed with an o-ring to provide secure bi-directional protection against contaminates.
  • Prevent the entry of water, dust, or other contaminants, ensuring a secure, reliable connection.
  • Used in threaded and non-threaded holes in applications such as cabinets or used in the automotive and electric industries.

Cap Head Seal Screws

This range of sealing screws has a cap head with a torx socket drive, incorporating an O-ring that is compressed-squeezed between the head, the socket drive and the mating surface to complete the seal. Manufactured from stainless steel, which provides good corrosion resistance and is slightly magnetic.

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. Clearance holes are recommended for optimal sealing performance (see measurements below). Clearance hole depth is 2-3 times the thread pitch; threads are metric coarse pitch.

Pan Head Seal Screws

This range of sealing screws has a pan head with three options: Torx drive, Philips drive and Slotted drive. Torx drive screws provide a positive, fast engagement that transmits torque with less downward pressure. Phillips drive screws can withstand high torque, making them a good choice for applications that require a tight fit and make it easy to remove the screw, even if it has been driven in tightly. Finally, slotted drive screws have a lower torque capacity than other drive types, such as Phillips or Torx.These screws incorporate an O-ring which is compressed and squeezed between the head and the mating component to complete a more secure seal. They are manufactured from stainless steel, which provides good corrosion resistance and is slightly magnetic.

  • It provides a secure and watertight connection to various applications, minimising the risk of loosening due to vibration or movement.
  • Used in threaded and non-threaded holes in applications such as cabinets or used in the automotive and electric industries.
  • Incorporate an O-ring which is compressed and squeezed between the head and the the mating surface to complete a more secure seal.
