S-92196A554 1/4"-20 x 3" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• Exceptional strength and durability with a 70,000 psi tensile strength and Rockwell B70 hardness, ensuring reliable performance under high-stress conditions.
• Precise and secure fastening achieved with a Class 3A thread fit, minimizing the risk of loosening and providing a tight, vibration-resistant connection.
• Easy installation and high torque capability enabled by the standard hex socket drive and 3/16" drive size, allowing for efficient assembly with common tools.
• Versatile coarse UNC thread design (1/4"-20) facilitates quick engagement and is less prone to cross-threading, speeding up assembly processes.
• Optimized for space-constrained applications with its low-profile socket head design, providing a flush finish where clearance is limited.
• Guaranteed compliance and reliability by meeting ASME B18.3 specifications, RoHS 3, and REACH regulations, ensuring product safety and environmental standards.

Professional Applications & Engineering Value

This Socket Head Cap Screw is engineered to address critical challenges in industrial assembly and machinery.
