Professional Applications & Engineering Value
This 6-32 UNC Class 3A set screw with Nylon Patch thread locker is engineered to address common industrial challenges like loosening under vibration and thermal cycling. Made from 18-8 Stainless Steel, it offers exceptional corrosion resistance for machinery, automotive, and electrical enclosures exposed to moisture or chemicals. The coarse UNC threads and Class 3A fit ensure tight tolerances and easy alignment, reducing assembly time and improving joint integrity. With a cup point that bites into materials without excessive marring, it's ideal for securing gears, pulleys, and collars where repositioning is infrequent. The hex drive and headless design allow for compact installations in confined spaces, delivering long-term reliability for OEM and MRO applications.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with UNC coarse threads in a Class 3A fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental and safety standards are upheld. The thread locker temperature range is rated from -70° to 250°F, supporting consistent performance across varied operating conditions.
