- Regulatory compliance meeting ASME B18.3 standards and environmental directives (RoHS 3 & REACH)
Professional Applications & Engineering Value
This hex headless set screw is engineered to address common industrial fastening challenges, such as component slippage and loosening under dynamic loads. The 18-8 stainless steel material offers excellent resistance to rust and chemical exposure, making it suitable for outdoor, marine, and chemical processing equipment. Its 90° cone point concentrates force to create a permanent, high-friction lock on shafts, collars, and pulleys, preventing rotational movement. The Class 3A thread fit and UNC coarse threads ensure quick, accurate installation with reduced risk of cross-threading, while the headless design allows for flush mounting in space-constrained assemblies. Ideal for securing gears, bearings, and other rotating parts in heavy machinery, automotive, and aerospace applications, this set screw delivers reliable performance where precision and durability are critical.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC coarse thread with Class 3A thread fit for precise dimensional accuracy and tight tolerances. It complies with ASME B18.3 manufacturing specifications, ensuring consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety standards for hazardous substances.
