Professional Applications & Engineering Value
This 1/2"-13 UNC Class 3A hex headless set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor conditions, while the coarse thread spacing ensures rapid installation and superior holding power in soft materials. The headless design with flat tip creates minimal surface disruption when securing pulleys, gears, and collars onto shafts, preventing slippage in high-torque applications. With Rockwell B80 hardness, this heavy-duty set screw maintains its mechanical properties under continuous stress, making it ideal for manufacturing equipment, automotive assemblies, and industrial machinery where reliability cannot be compromised.
Specification Summary & Compliance
This set screw features precision 1/2"-13 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and tight tolerances. Manufactured in compliance with ASME B18.3 standards for consistent quality and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for global industrial applications.
