Dome Nuts - Nylon

Dome Nuts, also known as Cap Nuts and Acorn Nuts, is a type of nut that has a domed end on one side. As such, a Dome Nut is ideal for covering and protecting a bolt or screw in a wide range of applications.

Made from Nylon 6/6, these Nylon Acorn Nuts not only protect the bold threads under the nut, but also provide a tidy appearance. A Cap Nut may also improve safey on some joints and applications. When an assembly needs a smooth finsih, or you wish to hide or disguise the fasteners and exposed threads of an application, Plastic Dome Nuts are the ideal solution.

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.

Integral Seal Hex Nuts

Integral Seal Nuts are a type of fastener with an integrated sealing feature, combining the functionality of a nut and a sealing component into a single unit. These nuts provide reliable protection while simplifying the assembly process and eliminating the need for additional sealing components. They prevent the entry of water, dust, or other contaminants providing bi-directional sealing.

This range of Integral Seal hexagonal nuts incorporates an O-ring which is compressed and squeezed between the nut and mating component.

They are suitable for temperatures from -100C to +260C and are reusable. Integral Seal Nuts are used in applications such as cabinets or used in the automotive, machinery and electric industries.
