Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to solve critical challenges in industrial assembly, such as shaft securing, pulley fastening, and gear positioning. The zinc plated alloy steel construction provides excellent resistance to rust and corrosion, which is vital for machinery operating in harsh conditions. The headless design and cup tip ensure a flush fit, minimizing protrusion and maximizing contact area for superior grip and vibration resistance. With a Class 3A thread fit and coarse UNC thread, it offers high precision and quick installation, reducing assembly time while maintaining a secure hold. This makes it an ideal choice for heavy-duty applications in automotive, manufacturing, and aerospace sectors where reliability is non-negotiable.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC coarse thread with a Class 3A thread fit for high precision and strength. It complies with ASME B18.3 specifications and is manufactured from zinc plated alloy steel with a Rockwell C45 hardness. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets environmental and safety standards for industrial use.
