Professional Applications & Engineering Value
This 2024 aluminum round head screw delivers exceptional engineering value where weight reduction and corrosion resistance are critical. The 1/4"-20 UNC coarse threading with Class 2A fit ensures reliable performance in vibration-prone applications while maintaining easy assembly. The slotted drive style provides compatibility with standard tools, making it ideal for maintenance and repair operations. With Rockwell B40 hardness and 30,000 psi tensile strength, this fastener withstands mechanical stresses in aerospace components, electronic enclosures, and marine equipment where aluminum's natural corrosion resistance prevents degradation in harsh environments. The fully threaded design maximizes clamping force distribution, making it particularly valuable in assemblies requiring uniform stress distribution across the fastened joint.
Specification Summary & Compliance
This 1/4"-20 UNC threaded screw features precise Class 2A thread fit tolerances and complies with ASME B18.6.3 dimensional standards. The manufacturing process adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory compliance. With dimensions of 1-1/2" length, 0.472" head diameter, and standardized rounded head profile, this fastener maintains consistent quality and performance across industrial applications.
