S-95198A309 10-24 x 5/16" ASME B18.3, DIN 912, ISO 4762 Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Reliable Sealing Performance: Integrated Buna-N rubber O-ring ensures leak-proof connections, ideal for hydraulic and pneumatic systems operating up to 1500 psi.
• Corrosion-Resistant Durability: 18-8 stainless steel construction provides excellent resistance to rust and chemical exposure in harsh industrial environments.
• Precision Thread Fit: Class 3A thread tolerance guarantees secure, vibration-resistant fastening with minimal risk of loosening under dynamic loads.
• High Tensile Strength: 100,000 psi tensile rating supports heavy-duty applications, reducing the risk of fastener failure in critical assemblies.
• Wide Temperature Compatibility: O-ring maintains elasticity from -40°F to 225°F, ensuring consistent sealing across diverse operating conditions.
• Standardized Socket Drive: Hex drive (5/32") allows for high-torque installation with common tools, preventing stripping and enabling space-efficient assembly.
• Global Compliance: Meets ASME B18.3, DIN 912, and ISO 4762 standards, with RoHS 3 and REACH compliance for unrestricted international use.

Professional Applications & Engineering Value

This socket head cap screw with 10-24 UNC coarse thread and integrated Buna-N O-ring addresses critical sealing challenges in pressurized systems. Engineered from 18-8 stainless steel, it combats corrosion in chemical processing, marine, and food equipment while the Class 3A thread fit ensures precise engagement in tapped holes, minimizing fluid leakage paths. The fully threaded design distributes clamping force evenly, making it ideal for compact assemblies in pumps, valves, and machinery housings where 1500 psi pressure ratings and temperature fluctuations from -40°F to 225°F are common. Its standard socket head profile facilitates installation in confined spaces, reducing assembly time and maintenance costs.

Specification Summary & Compliance

This screw maintains Class 3A thread tolerance per UNC standards, with a 5/16" length and coarse thread spacing for rapid installation. Manufacturing adheres to ASME B18.3, DIN 912, and ISO 4762 specifications, ensuring dimensional consistency. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of restricted substances, supporting use in regulated industries.
