Integral Seal Bolts

Sealing bolts 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.

This range of sealing bolts with a hexagonal head, incorporates an O-ring which is compressed, squeezed into a precision groove machined under the head of the bolt, and the mating surface to complete the seal. They are manufactured from stainless steel, which provides good corrosion resistance and is slightly magnetic.

Integral Seal Bolts are used in threaded and non-threaded holes in applications such as pipes, valves or pumps. Sealing bolts 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 bolts 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 a sealing feature to provide a secure and watertight connection to various applications, minimising the risk of loosening due to vibration or movement.

• Prevent the entry of water, dust, or other contaminants, ensuring a secure, reliable connection.

• It has a hexagonal head and incorporates an O-ring which is compressed, squeezed between the head and the mating surface.
