The rubber O ring sits in a precision machined groove under the screw head. As you tighten the screw, the O ring gets squeezed between the screw head and the surface. This creates a 360 degree seal that keeps water, dust, and moisture out.
The most common style. Works with standard cross tip screwdrivers.
Features a built in washer flange. Provides wide clamping pressure without needing a separate washer.
Has an internal hex drive. Use an Allen key for higher torque transmission.
Offers good oil resistance for general purpose use.
Performs well across a wide temperature range from -50°C to 200°C.
Provides excellent weather resistance for outdoor applications.
Offers superior chemical resistance for harsh environments.
Stainless Steel 304: Offers good corrosion resistance for outdoor and wet areas.
Stainless Steel 316: Provides enhanced resistance for marine environments.
Zinc Plated Carbon Steel: Provides good strength at a cost effective price point.
Metric sizes M4 M5 M6. Standard lengths from 6mm to 30mm. Custom sizes available for OEM orders.
IP67 Rated: Screws can withstand immersion in water up to 1 meter for 30 minutes.
IP68 Rated: Screws can withstand continuous immersion under pressure.
Self sealing screws are widely used for outdoor electrical enclosures, junction boxes, electric meters, gas meters, marine equipment, automotive lighting, and industrial control panels where water and dust protection is critical.
All self sealing screws undergo O ring integrity testing and thread gauging. ISO 9001 certified quality management system. Various protection ratings available. Custom manufacturing for special head styles and sealing materials. Bulk wholesale pricing with factory direct shipping worldwide.
A rubber O-ring sits in a precision machined groove under the head. As the screw is tightened, the O-ring is compressed against the mating surface, forming an immediate 360-degree watertight and dust-tight seal without external sealants.
They are available in Phillips pan head for standard cross-tip screwdrivers, Hex washer head for wide clamping pressure without separate washers, and Hex socket head for high-torque applications using an Allen key.
Silicone O-rings are ideal for temperatures from -50°C to 200°C, Viton offers superior chemical resistance, EPDM rubber provides high weather resistance, and Nitrile rubber (NBR) delivers optimal oil resistance.
IP67 rated screws withstand water immersion up to 1 meter for 30 minutes, whereas IP68 rated screws are engineered to withstand continuous immersion under higher pressure.
Stainless steel 304 is available for outdoor and wet areas, stainless steel 316 provides enhanced resistance for marine conditions, and zinc plated carbon steel is available for cost-effective strength.
Yes. Standard sizes include metric M4, M5, and M6 with lengths from 6mm to 30mm, and custom sizing, head designs, and specific seal materials can be manufactured for OEM requirements.
