Self-sealing screws and nuts provide reliable protection against penetrating fluids and gases

Self-sealing screws and nuts are used in many areas, for example, in hydraulic systems, medical equipment or tank containers. They should be used everywhere, where it would otherwise be possible for fluids and gases to penetrate the components unintentionally. These special screws and nuts by APM Hexseal have a specific, patented O-ring that provides full protection and still enables complete metal-on-metal mounting. This way the tightness of the seal is guaranteed and the detaching of the screws due to vibration is prevented. We supply a whole range of different self-sealing screws and nuts that are all UL-approved:

  • different lengths and sizes
  • different materials
  • diverse screw head shapes

A further advantage of the self-sealing screws and nuts is that they can be used several times over and so are extremely durable, due to the excellent finishing of the sealing ring (O-ring) so that they cannot loosen. That means that the seal is significantly more effective than with alternative methods, for example the sued of adhesives.

At ALDERS you can find self-sealing screws and nuts with pure thread seals, bell seals and dome seals.
