High-Performance Sealing Mechanism: This self-sealing screw features a rubber O-ring engineered directly onto the shaft. Upon tightening, the O-ring is compressed between the screw head and mating surface, forming a dependable seal that reliably blocks moisture, water, and dust ingress.
Efficient One-Step Assembly: Eliminates the necessity for standalone sealing washers or messy liquid sealants. Installation is completed seamlessly in a single step using standard manual or power drive tools.
Designed specifically for environments prone to humidity and moisture exposure, these fasteners are exceptionally suited for outdoor electrical enclosures, marine systems, automotive lighting assemblies, solar panel junction boxes, and industrial factory control consoles.
Available in a broad selection of head designs, including Phillips pan head, flat countersunk head, and hex head. Standard metric thread diameters range from M3 through M8. Screw bodies are crafted from premium grade 304 or 316 stainless steel, offering outstanding defense against rain, salt fog, and aggressive outdoor atmospheres.
To accommodate demanding thermal and chemical conditions, alternative elastomer O-ring configurations including silicone and Viton are readily supplied upon specification.
