Pan Head Seal Screws

En stock En producción

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.

This seal screws with a pan head 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.
