An ordinary screw lacks seal protection, allowing dirt, fluids, gases etc. to infiltrate and damage sensitive devices. Sealing screws provide bi-directional sealing protection to systems where screws are used, to protect them against foreign contaminates, which, with a standard fastening may penetrate or leak and cause damage.
The seal screws incorporate an O-ring underneath the screw, bolt etc. which forms a sealant layer. The seal provides bi-directional sealing. The screws are very easy to use and do not need any special preparation or re-tightening
Automotion Components self sealing fasteners are designed and manufactured with a precision engineered groove beneath the head of the fastener. As the fastener is tightened, the O-ring is compressed, squeezing the O-ring between the groove and mating surface to complete the seal. The design of the groove controls the amount of compression of the O-ring and because O-rings retain their elastic memory, the screws are reusable time after time. There are a range of O-ring materials that can resist virtually all chemical and environmental conditions. We can also provide sealing screws (on request) to military specifications (MILSPEC).

|Hexagonal||Ideal for precision assembly. Most recommened where less surface area is available.|
|Most recommended drive type. Provides good control in |
driving. Always use a driver bit of the proper size which is in
|Positive-engaging, fast-locating method which transmits |
drive torque with less required downward pressure. Good
|Slotted||Accepts standard blade screwdriver. |
Requires less downward pressure to drive parts than those with recessed openings.
Use proper fitting blade to minimize slippage.
|Hex flange||Accepts hex wrench. Slotted drive is added to make it easier to remove the fastener (if required).|
|Security||These screws are impossible to remove without the special matching screwdriver.|
We can provide Torx® heads and security/tamper-proof screws, as well as special threads, grooves and cross holes for safety wires, and a further range of styles such as captive screws, anti-vibration strips on the threads etc (for extrene vibration applications).
Some of the typical applications for our sealing screws include:
We are entering the next phase of our relocation to a larger factory in Chichester, West Sussex. The next few weeks will see products start to be moved from our current site in Cranleigh, Surrey to the new warehouse.
There are thousands of parts to be relocated and whilst we are doing our best to ensure a smooth transition, this may cause slight delays to some shipments.
We expect to be have all parts relocated and full production capability for our new 35,000ft² facility running by mid-March. Thank you for your understanding.Continue to Website
