Professional Applications & Engineering Value
This hex headless set screw is engineered to address common industrial challenges like vibration loosening and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it suitable for machinery, automotive, and outdoor equipment applications. The extended tip increases surface contact, enhancing grip on shafts and collars, while the coarse UNC thread allows for quicker installation and higher torque transmission. With a right-hand thread direction and Class 3A thread fit, it ensures tight tolerances and reliable performance in high-stress environments, reducing maintenance needs and downtime.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 standards, with a 1/2"-13 UNC coarse thread and Class 3A thread fit for precise dimensional accuracy. The extended tip features a diameter of 0.343" and length of 0.13", with tight tolerances as specified. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory alignment for global industrial use.
