Professional Applications & Engineering Value
This zinc-plated alloy steel flat head screw is engineered to solve critical fastening challenges in industrial settings. Its high tensile strength of 130,000 psi and Rockwell C39 hardness provide exceptional resistance to shear and tensile forces, preventing failure in heavy-duty assemblies. The UNC coarse thread and Class 3A fit ensure rapid installation and a secure, vibration-resistant connection, ideal for machinery, metal frameworks, and automotive components. The 82° countersink angle allows the screw to sit flush with surfaces, reducing snagging and improving safety. The zinc plating offers a protective barrier against corrosion, making these flat head screws a reliable choice for both indoor and outdoor applications, from manufacturing equipment to structural supports.
Specification Summary & Compliance
This product features a 6-32 UNC coarse thread with a Class 3A thread fit for high precision. It is manufactured to meet ASTM F835 specifications, ensuring consistent quality and performance. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
