Professional Applications & Engineering Value
These 3/8"-16 UNC flat head screws deliver critical engineering solutions where surface-flush fastening and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, equipment assemblies, and structural frameworks exposed to industrial atmospheres. The coarse UNC threading ensures rapid installation and superior resistance to vibrational loosening in dynamic applications. With full threading along the 1 3/4" length, these screws maintain consistent clamping force across the entire engagement area. The Rockwell B70 hardness rating guarantees dimensional stability under load, making them ideal for automotive components, manufacturing fixtures, and construction applications where 60,000 PSI tensile strength is required to prevent joint failure.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerances ensuring interchangeability and proper mating with standard nuts. These flat head screws conform to ASME B18.6.3 mechanical standards and feature right-hand UNC coarse threads (3/8"-16). Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, confirming they contain no restricted substances for industrial use worldwide.
