Professional Applications & Engineering Value
This 316 Stainless Steel serrated flange locknut delivers critical vibration resistance in demanding applications where fastener integrity is paramount. The serrated locking mechanism creates permanent resistance to rotational loosening under dynamic loads, making it ideal for heavy machinery, automotive assemblies, and structural frameworks. Engineered with UNC coarse threads and Class 2B thread fit, it maintains consistent clamping force while accommodating minor misalignments. The external hex drive combined with the 1/2" flange provides both installation convenience and superior load distribution, eliminating the need for separate washers. Manufactured from corrosion-resistant 316 stainless steel, this flange nut withstands aggressive environments including chemical processing and outdoor exposure, ensuring long-term reliability.
Specification Summary & Compliance
This flange locknut features 10-24 UNC coarse threads with Class 2B thread fit for consistent engagement and right-hand threading direction. Critical dimensions include 1/2" flange diameter, 3/8" width across flats, and 7/32" height. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring adherence to hazardous substance restrictions for industrial applications.
