S-92205A227 M5 x 18 mm Sealing Hex Head Screws

Key Features & Benefits at a Glance

• Superior Sealing Performance: Integrated silicone O-ring provides reliable leak-proof sealing in high-pressure environments up to 20,000 psi, reducing maintenance and downtime.
• Exceptional Corrosion Resistance: Made from 18-8 stainless steel, offering excellent durability against rust and chemical exposure in harsh industrial settings.
• Wide Temperature Tolerance: Silicone seal maintains integrity across extreme temperatures from -80° to 400° F, ensuring consistent performance in varied operating conditions.
• High Tensile Strength & Hardness: 80,000 psi tensile strength and Rockwell B85 hardness deliver robust fastening that resists stripping and deformation under heavy loads.
• Precision Thread Fit: Class 6g thread tolerance ensures easy installation and secure, vibration-resistant connections in metric assemblies.
• Convenient External Hex Drive: Standard hex head allows for quick tightening with common tools, speeding up assembly and reducing labor time.
• Full Thread Engagement: Fully threaded design maximizes grip and distribution of clamping force for enhanced joint stability.

Professional Applications & Engineering Value

This M5 hex head screw with silicone O-ring seal is engineered to solve critical sealing challenges in high-pressure industrial applications, such as hydraulic systems, pneumatic equipment, and fluid handling assemblies. The 18-8 stainless steel construction provides inherent corrosion resistance, ideal for environments exposed to moisture, chemicals, or outdoor elements, while the coarse metric thread (M5 x 0.8 mm) and Class 6g fit ensure reliable engagement in tapped holes, minimizing the risk of cross-threading. The silicone rubber O-ring effectively seals against leaks even under fluctuating temperatures and pressures, reducing the need for additional gaskets or sealants. This combination of material durability and sealing features makes it a cost-effective solution for OEMs and maintenance teams seeking to enhance equipment reliability and comply with industry standards for safety and performance.
