Professional Applications & Engineering Value

This 1/2"-13 UNC hex headless set screw is engineered to address critical industrial fastening challenges where space constraints and vibration resistance are paramount. The headless design allows for flush mounting in tight assemblies, while the coarse UNC thread and Class 3A fit provide superior resistance to loosening under dynamic loads. Made from 18-8 stainless steel, it offers excellent corrosion resistance in moist or chemical-exposed environments, reducing maintenance needs. The 118° cone point ensures maximum bite into shafts and collars, preventing rotational slippage in power transmission systems, machinery, and precision equipment. Ideal for permanent or semi-permanent applications, this screw delivers reliable performance in automotive, aerospace, and manufacturing sectors where industrial set screws must withstand heavy-duty cycles.

Specification Summary & Compliance

This set screw features a 1/2"-13 UNC coarse thread with Class 3A thread fit for high precision and tight tolerances. It complies with ASME B18.3 manufacturing specifications, ensuring dimensional accuracy and interchangeability. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety standards for hazardous substances.
