PACK OF 10 Nylon Insert LOCK NUTS - US - 7/16"-14 UNC Thread Diameter: 7/16 Inch Pitch: 14 Thread per Inch COARSE (UNC) Low Strength GRADE A Head Style: NyLock Driver Size: 11/16 Inch Yellow Zinc CR+6 ASME B18.16.6. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coarse thread is beneficial, because they are less likely to cross thread, more tolerant in adverse conditions and facilitate quick assembly. Yellow-Zinc plated offers superior corrosion resistance in wet environments, better than zinc.. Locknuts have a locking feature to resist loosening under vibration. A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. The nylon insert compresses to securely fasten the nut against the bolt, ensuring resistance to vibration and loosening.. These Low-Strength steel locknuts have about half the strength of medium-strength steel locknuts, they're for light duty fastening applications, such as securing access panels. Combine with bolts that have similar strength. All are reusable but lose holding power after each use.. U.S.A Sourced Product.
