Cap Head Seal Screws

In production

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.

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. 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.
