Professional Applications & Engineering Value

This 3/8"-16 UNC flat head screw in 316 stainless steel with passivated finish addresses critical engineering challenges in corrosive environments. The combination of 70,000 psi tensile strength and Rockwell B80 hardness ensures structural integrity under heavy loads, while the fully threaded coarse UNC design provides superior pull-out resistance. The 82° countersink angle and flat head profile create seamless surface finishes in machinery, marine equipment, and chemical processing applications where corrosion resistance and reliability are paramount. These industrial screws maintain performance in saltwater, chemical exposure, and high-humidity conditions where ordinary fasteners would fail.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precise dimensional accuracy. The UNC 3/8"-16 coarse thread pattern ensures compatibility with standard components. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for regulated industries requiring verified material safety and environmental responsibility.
