S-90600A050 3/8"-16 x 2" ASME B18.3, ASTM F879 Stainless Steel Button Head Torx Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh environments
• Enhanced torque transmission and strip-out resistance from the T45 Torx drive for reliable, high-torque assembly
• Precise, secure thread engagement with UNC Class 3A fit, ensuring consistent clamping force and vibration resistance
• Full thread length provides maximum grip and load distribution along the entire fastener length
• High tensile strength of 60,000 psi supports demanding applications and heavy-duty assemblies
• Smooth, low-profile rounded button head reduces snagging and offers a finished appearance
• Compliance with ASME B18.3 and environmental regulations guarantees quality, safety, and global supply chain acceptance

Professional Applications & Engineering Value

These 3/8"-16 UNC Class 3A fully threaded screws are engineered to address critical challenges in industrial assembly, including corrosion-induced failure and torque inconsistency. The 18-8 stainless steel material combined with a passivated finish provides exceptional resistance to rust and chemicals, making them suitable for outdoor equipment, marine hardware, and food processing machinery. The T45 Torx drive minimizes cam-out, allowing for higher torque application without damaging the fastener head, which is crucial in automated or high-volume production lines. The rounded button head design not only enhances aesthetics but also reduces the risk of injury and interference in confined spaces. By ensuring reliable performance in heavy-duty fastening applications, these screws help maintain structural integrity and reduce maintenance costs over time.
