Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 6061 aluminum rounded head screws combine lightweight properties with exceptional 40,000 psi tensile strength, making them ideal for applications where weight reduction is critical without compromising structural integrity. The UNC coarse thread configuration ensures rapid installation and reliable performance in softer materials, while the integrated flange provides superior load distribution, eliminating the need for separate washers and reducing assembly time. The hex drive design offers positive torque transmission, minimizing cam-out issues common in production environments. These fully threaded screws deliver consistent fastening performance across electronics enclosures, machinery panels, and aerospace components where aluminum fasteners must meet strict weight and corrosion resistance requirements.
Specification Summary & Compliance
This 8-32 UNC coarse thread screw features precision Class 2A thread fit tolerances with right-hand threading and full-length engagement. Manufactured from 6061 aluminum with Rockwell B40 hardness, the fastener maintains dimensional accuracy across all critical parameters including 0.25" head diameter and 1/2" length. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(b)-II and meets REACH (EC 1907/2006) requirements, ensuring regulatory acceptance for international industrial applications.
