For purely sealing requirements, however, a range of products and processes are specifically available – like sealing the thread or applying under-head coatings.
Special coatings can also offer insulating properties.
An overview of the various sealing and insulating options is provided below.
Processes, functional security and costs are all under close control when spedseal is used as an integral part of the fastener. These multi-functional coatings can be applied to the shank or the underside of the fastener head – depending on the specific application requirements.
Fasteners coated with spedcaps are ideal for sealing connections; above all under dynamic load (axial to the fastener connection), these coated fasteners fulfil the most demanding requirements.
Fasteners coated in spedlack or spedstop offer a simple, secure solution to the sealing needs of numerous connections.
Among the numerous advantages are:
