Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat head screws deliver critical corrosion resistance where moisture, chemicals, or outdoor exposure threaten fastener integrity. The UNC coarse thread design ensures rapid installation and reliable performance in materials prone to stripping, while the fully threaded configuration maximizes pull-out resistance in demanding assemblies. Engineered with an 82° countersink angle and oval head profile, they provide flush mounting solutions for machinery, enclosures, and structural components where protruding fasteners are unacceptable. The combination of 80,000 psi tensile strength and Rockwell B80 hardness makes these Phillips drive screws ideal for vibration-resistant connections in manufacturing equipment, automotive subsystems, and electrical panel applications where long-term reliability is non-negotiable.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerances and UNC coarse thread specifications. These 1 3/4" flat head screws comply with ASME B18.6.3 mechanical and dimensional requirements, ensuring interchangeability and performance consistency. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance adherence for global market applications.
