316 304 Stainless Steel Sealing Screws Pan Head Phillips Rubber O Ring IP67 Waterproof For Electronics Enclosure
What is a sealing screw
A sealing screw is a fastener with a rubber O-ring or sealing washer pre-installed under the head. This design eliminates the need for additional sealant or separate washers. During installation, as the screw is tightened, the rubber seal is compressed between the screw head and the mating surface, forming a reliable watertight and dust-tight barrier.
How does it work
You drive the screw in. The rubber ring gets squeezed between the head and the surface. It fills every gap. Water cannot get through. Dust cannot get through.
What head styles do you have
- Phillips pan head – Standard cross drive. Works with any Phillips screwdriver.
- Flat head – Flat top with 82 degree cone, sits flush with the surface for a smooth finish.
- Hex socket head – Uses an Allen key. Good for tight spots where a screwdriver won't fit.
