Professional Applications & Engineering Value

These zinc-plated steel rounded head screws provide critical solutions for industrial assembly challenges where corrosion resistance and structural integrity are paramount. The combination of 60,000 psi tensile strength and Rockwell B70 hardness makes them ideal for heavy-duty applications in machinery, equipment manufacturing, and structural frameworks. The UNC coarse threading ensures rapid installation in metal, plastic, and composite materials, while the pan head profile offers a low-profile finish that resists snagging. Phillips drive compatibility with standard No. 2 bits streamlines production processes, reducing labor costs and installation errors in high-volume manufacturing environments.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (6-32 size) and 3-1/2" fully threaded length. These screws conform to ASME B18.6.3 mechanical standards and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring they are free from hazardous substances and suitable for global industrial applications.
