Professional Applications & Engineering Value
This 3/8"-16 UNC slotted screw is engineered for demanding applications where reliability is non-negotiable. The 18-8 Stainless Steel material, enhanced by a passivated finish, provides exceptional resistance to oxidation and chemical exposure, making it suitable for machinery, marine hardware, and food processing equipment. The rounded fillister head with its high, narrow profile offers a greater bearing surface and allows for a deeper slotted drive, which minimizes tool slippage and head stripping during high-torque installation. The coarse thread and Class 2A fit facilitate quick assembly and maintain a secure hold even in environments prone to vibration, reducing maintenance needs and downtime.
Specification Summary & Compliance
This screw adheres to a Class 2A thread fit for standard clearance and ease of assembly. It is manufactured to the dimensional requirements of ASME B18.6.3 and features a 3/8"-16 UNC coarse thread profile. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious industrial supply chains.
