Professional Applications & Engineering Value
This black oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and precise component positioning are critical. The extended tip design creates superior surface contact, preventing movement in pulleys, gears, and collars while the UNF fine threads maintain tight tolerances under dynamic loads. The Rockwell C45 hardness ensures the fastener withstands repeated adjustments without deformation, making it ideal for machinery maintenance, automotive assemblies, and precision equipment. The hex drive configuration allows for high-torque installation in confined spaces, while the corrosion-resistant black oxide finish extends service life in challenging environments.
Specification Summary & Compliance
This precision fastener features 5/16"-24 UNF Class 3A threads with fine thread spacing and right-hand orientation, manufactured to exacting dimensional standards. The extended tip maintains tight tolerances with diameter of 0.203" (-0.008" to 0") and length of 0.082" (-0.005" to 0"). Compliance includes ASME B18.3 specifications (ASTM F912), along with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial applications.
