Professional Applications & Engineering Value
These 1/2"-13 UNC flat head screws deliver critical performance where flush surface requirements meet demanding mechanical loads. The 18-8 stainless steel composition, enhanced by passivated finish, provides exceptional resistance to corrosion and chemical exposure in manufacturing, marine, and food processing equipment. The coarse UNC threading with Class 3A fit ensures rapid assembly and maintains integrity under vibration, while the hex drive design allows high-torque installation without stripping. Engineered for machinery frames, structural components, and precision equipment where flat head profile eliminates protrusions, these industrial screws combine dimensional accuracy with 70,000 psi tensile strength for long-term reliability in heavy-duty fastening applications.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerance for precision engagement. Features 1/2"-13 UNC coarse threads in right-hand direction, 82° countersink angle, and full threading along 1-1/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Material certification includes Rockwell B55 hardness and 70,000 psi tensile strength verification for quality assurance in inch system applications.
