Professional Applications & Engineering Value
This 3/8"-16 UNC T45 Torx Rounded Head Screw in 18-8 stainless steel is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The passivated finish significantly enhances corrosion resistance, making it suitable for applications in marine, chemical processing, and outdoor equipment where moisture and chemicals are prevalent. Its T45 Torx drive ensures maximum torque transfer without slippage, reducing tool wear and improving worker safety. The UNC coarse thread and Class 3A thread fit provide quick engagement and a secure hold, ideal for machinery, automotive assemblies, and structural frameworks that require reliable, repeatable fastening. With partial threading, it offers precise clamping force control, preventing over-tightening and material damage in sensitive components.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. Thread standards include 3/8"-16 UNC with a Class 3A thread fit for tight tolerances and coarse spacing. It is manufactured from 18-8 stainless steel with a passivated finish, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental and safety standards.
