Sealing Fasteners
Sealing fasteners are designed to protect against harsh climates, moisture, gases, dirt and other contaminations from passing though the joint between the fastener and the application. Fastenright supplies sealing screws, bolts, nuts, and security fasteners for applications where the fixing needs to provide both mechanical fastening and environmental sealing.
The range uses a pre-assembled rubber O-ring beneath the fastener head or contact surface. When installed, the O-ring forms a seal around the fixing point while allowing metal-to-metal contact between the components.

Sealing Fasteners for Industrial Applications
Sealing fasteners are suitable for applications where exposure to moisture, harsh environmental conditions or contaminants could affect the joint. The sealing element can also compensate for tolerance run-out, helping maintain the seal where there are variations in the mating surfaces.
Fastenright supplies sealing fasteners in a range of types and sizes, including:
- Sealing screws
- Sealing bolts
- Sealing nuts
- Security sealing fasteners
The range includes different materials, sizes and configurations, with specialist options available for more demanding applications.
Benefits of Sealing Fasteners
Sealing fasteners can provide several advantages over using a separate sealing component alongside a conventional fastener. The sealing element is supplied pre-assembled, making the fixing straightforward to install without specialist installation tools.
Depending on the application, sealing fasteners can provide:
- Protection against water and moistureย
- Resistance to dirt and other contaminants
- Resistance to harsh environmental conditions
- 360-degree multidirectional sealing
- Compensation for tolerance run-out
- Metal-to-metal contact
- Reusable fixing capability within appropriate limits
- No requirement for additional specialist installation equipment
Fastenright can supply sealing fasteners for standard requirements as well as special sizes and configurations to order.
