Professional Applications & Engineering Value
These 7075 aluminum socket head cap screws deliver exceptional performance in precision engineering applications where weight reduction and corrosion resistance are critical. The 2-56 UNC coarse threads with Class 3A fit provide superior thread engagement in aluminum and soft material applications, preventing stripping while maintaining precise alignment. The 5/64" hex drive socket head design ensures maximum torque transmission without cam-out, making these fasteners ideal for aerospace components, electronic enclosures, and precision instrumentation. The fully threaded construction distributes clamping force evenly across the entire 1/8" length, solving common challenges with shallow mounting depths in compact assemblies. With RoHS 3 and REACH compliance, these screws meet the strictest environmental regulations for industrial and electronic applications.
Specification Summary & Compliance
This socket head cap screw features precision 2-56 UNC coarse threads with Class 3A fit tolerance for superior thread engagement. The inch system fasteners maintain exacting dimensional standards with 9/64" head diameter and standard socket head profile. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance-free construction. The right-hand thread direction and fully threaded rod type provide consistent performance across industrial applications requiring reliable fastening solutions.
