- High mechanical strength and durability provided by Rockwell B80 hardness, resisting wear and deformation under load
- Secure, high-torque installation enabled by the 3/16" hex drive, allowing for precise tightening in confined spaces
- Effective surface grip and component alignment from the cup tip design, minimizing slippage and damage to shafts
- Broad industry compatibility with compliance to ASME B18.3 standards, ensuring dimensional accuracy and interchangeability
- Safe for regulated applications as it is RoHS 3 and REACH compliant, meeting strict environmental and safety directives
Professional Applications & Engineering Value
This 18-8 stainless steel set screw is engineered to address critical challenges in precision assembly and machinery. Its UNF fine thread and Class 3A fit provide exceptional clamp load retention, effectively resisting loosening under vibration in motors, gearboxes, and rotating shafts. The headless design with a hex drive allows for flush mounting in space-constrained applications, while the cup tip concentrates force for a secure bite on components, preventing misalignment. Made from corrosion-resistant stainless steel, it ensures long-term reliability in demanding environments like marine, automotive, and food processing equipment, reducing maintenance frequency and downtime.
Specification Summary & Compliance
This set screw features a 3/8"-24 UNF fine thread with a Class 3A thread fit for high precision and strength. It adheres to the ASME B18.3 standard for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
