Stainless Steel 304 Sealing Screws Phillips Pan Head With Rubber O Ring IP67 Waterproof For Electronics Enclosure
Self sealing screws are fasteners with a pre installed rubber O ring or sealing washer under the screw head. When you drive the screw in, the rubber compresses against the surface and creates a watertight and dust tight seal. No need for extra sealant or separate sealing washers.
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.
Phillips pan head is the most common. Works with standard cross tip screwdrivers.
Hex washer head has a built in washer flange. Provides wide clamping pressure without needing a separate washer.
Hex socket head has a hex drive inside. Use an Allen key for higher torque.
Nitrile rubber (NBR) O ring offers good oil resistance for general purpose use.
Silicone O ring performs well across a wide temperature range from -50°C to 200°C.
EPDM rubber washer provides excellent weather resistance for outdoor applications.
Viton O ring offers superior chemical resistance for harsh environments.
Stainless steel 304 self sealing screws offer good corrosion resistance for outdoor and wet areas. Stainless steel 316 provides enhanced resistance for marine environments.
Zinc plated carbon steel self sealing screws provide good strength at a cost effective price point.
