• Rockwell B69 hardness offers excellent durability and resistance to wear and deformation
• Class 2A thread fit with UNC coarse threading ensures easy installation and secure fastening in various materials
• Fully threaded design maximizes grip and holding power across the entire screw length
• Phillips No. 2 drive allows for efficient torque application and reduced cam-out during installation
• Rounded head profile provides a finished appearance and minimizes snagging in assembled products

Professional Applications & Engineering Value

These 8-32 UNC zinc-plated steel rounded head screws are engineered to address critical industrial fastening challenges, particularly where corrosion resistance and high tensile strength are paramount. The zinc-plated finish protects against oxidation in humid or outdoor environments, while the coarse UNC threading ensures rapid installation and reliable performance in metal, plastic, and wood assemblies. With a fully threaded design and Phillips drive, they provide consistent clamping force and reduce assembly time in manufacturing lines, electrical enclosures, machinery, and automotive components. Their 60,000 psi tensile strength makes them suitable for heavy-duty applications where vibration resistance and structural integrity are essential.

Specification Summary & Compliance

These screws feature precision Class 2A thread fit with UNC coarse threading (8-32 size) and comply with ASME B18.6.3 manufacturing standards for dimensional accuracy. They are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
