Professional Applications & Engineering Value

This M6 socket head cap screw with Buna-N O-ring sealing addresses critical fluid containment challenges in industrial applications where pressure integrity is paramount. The 18-8 stainless steel material provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor conditions, while the partially threaded design offers optimal grip strength where full threading isn't required. The metric coarse thread with Class 6g precision ensures reliable engagement in aluminum, steel, and engineered materials, preventing cross-threading and ensuring consistent clamp load. Engineered for hydraulic systems, pneumatic equipment, and precision machinery, this sealing screw delivers reliable performance where conventional fasteners would fail under pressure or temperature extremes.

Specification Summary & Compliance
