S-96452A619 3/8"-16 x 1/2" ASME B18.3, ASTM F835 Steel Button Head Torx Plus Screws

Key Features & Benefits at a Glance

• Superior torque transmission and slip resistance with the Torx Plus IP45 drive system, reducing tool wear and preventing fastener damage during high-torque applications.
• Enhanced corrosion resistance and durability thanks to the Black-Oxide finish on Alloy Steel, providing a protective layer for extended service life in demanding environments.
• Exceptional mechanical strength and reliability with a tensile strength of 120,000 psi and Rockwell C39 hardness, ensuring the screw withstands heavy loads and high-stress conditions.
• Precise and secure fastening achieved through Class 3A thread fit and UNC coarse threads, offering excellent vibration resistance and reducing the risk of loosening.
• Easy installation and flush mounting with a low-profile rounded (button) head design, ideal for applications where a smooth surface finish is required.
• Full compliance with industry standards, including ASME B18.3, ensuring consistent quality, dimensional accuracy, and interoperability in professional assemblies.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting strict regulations for hazardous substances and supporting sustainable procurement.

Professional Applications & Engineering Value

This 3/8"-16 Torx Plus Black-Oxide Alloy Steel Rounded Head Screw is engineered to solve critical challenges in industrial and mechanical assemblies. The Torx Plus T45 drive system delivers maximum torque transfer, minimizing cam-out and tool slippage, which is vital for high-tension applications in machinery, automotive, and construction sectors. The Black-Oxide surface treatment on the Alloy Steel provides a robust barrier against rust and wear, extending the fastener's lifespan even in harsh conditions. With UNC coarse threads and a Class 3A thread fit, it ensures quick installation and reliable holding power, reducing maintenance needs in vibrating environments. Fully threaded for consistent grip, this screw is ideal for securing heavy-duty components where strength, precision, and compliance with standards like ASME B18.3 are non-negotiable.
