S-92845A766 1/2"-13 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability
• Precise, secure fastening ensured by Class 3A thread fit, minimizing the risk of loosening under vibration
• High mechanical strength from Rockwell B80 hardness, providing excellent resistance to wear and deformation
• Optimized for high-torque applications with a 1/4" hex drive, allowing for easy installation and removal without stripping
• Enhanced gripping power due to the extended tip design, which increases surface contact and prevents component slippage
• Reliable performance in automated assembly thanks to tight diameter and length tolerances on the tip for consistent placement
• Broad industrial compliance meeting ASME B18.3 standards, RoHS 3, and REACH, ensuring safety and regulatory acceptance

Professional Applications & Engineering Value

This 1/2"-13 UNC hex headless set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. The 18-8 Stainless Steel material offers excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and outdoor equipment where exposure to moisture is common. The extended tip and coarse thread spacing provide superior holding force, preventing axial movement in pulleys, gears, and collars. With a Class 3A thread fit and right-hand thread direction, it ensures tight, reliable fastening that withstands high vibration and dynamic loads, reducing maintenance needs and downtime in production environments.

Specification Summary & Compliance

This set screw features a 1/2"-13 UNC thread with Class 3A precision fit and coarse thread spacing for robust engagement. Tip dimensions include a diameter of 0.343" with tight tolerances (-0.009" to 0") and length of 0.13" (-0.005" to 0"), ensuring consistent performance. Manufactured in compliance with ASME B18.3 specifications, it is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety standards for industrial use.
