Stainless Steel 304 Sealing Screws Phillips Pan Head With Rubber O Ring IP67 Waterproof For Electronics Enclosure

Sealing screws are basic but critical parts for keeping your equipment working well. They stop water, dust, and oil from getting in. As a Chinese supplier, we make waterproof and self-sealing screws in common sizes like M2, M3, M4, M5, and M6. We also offer O-ring, socket cap, and tamper-proof styles.

These screws do two jobs: they fasten parts and seal them. They come with pre-installed O-rings (silicone, NBR, or EPDM). When tightened, the ring compresses to form a tight seal, so you don’t need extra washers or glue.

This model is a metric pan head Torx sealing screw with an O-ring, made to DIN standards. The drawing shows all key details clearly—head size, drive type, thread length, and seal dimensions. Use it to pick the right size or plan tooling.

We use quality stainless steel or carbon steel with zinc, nickel, or black oxide finishes to resist rust. O-rings are available in three types: silicone (high heat), EPDM (outdoor use), and NBR (oil-heavy jobs).

The one-piece design saves time and cost. The seal stays tight even under vibration. Every batch is tested for waterproof performance, strength, and durability to meet global standards.

These screws work for electronics, outdoor lights, solar gear, plastic parts, industrial machines, and security devices. They’re great for enclosures, housings, and precision parts that need to stay sealed.
