Professional Applications & Engineering Value
This 8-32 UNC brass set screw is engineered to address critical challenges in precision assembly and maintenance. The headless design and compact 3/16" length make it perfect for applications where space is limited and a flush finish is required. The combination of Class 3A thread fit and coarse thread spacing ensures rapid installation and superior resistance to loosening under dynamic loads, which is vital in machinery, automotive components, and electronic enclosures. The hex drive provides a secure grip for high-torque fastening, while the brass material offers inherent corrosion resistance and non-magnetic properties, making it indispensable in electrical systems and marine environments. This screw delivers reliable, long-term performance where precision and material compatibility are paramount.
Specification Summary & Compliance
This set screw features a 0.164" thread diameter with UNC coarse threading and a precision Class 3A thread fit for tight tolerances and reliable performance. It is manufactured in compliance with the ASME B18.3 standard, ensuring consistent quality and dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use worldwide.
