50Pcs Zinc Hex Thread Cutting Fasteners are engineered for high-strength, precision fastening in demanding environments. Designed with a 6.3mm stud size, 11mm hex size, and a durable 18mm flange diameter, these premium hardware components deliver exceptional grip and stability. The zinc finish provides superior corrosion resistance, extending the lifespan of the fasteners in both indoor and outdoor conditions.
Featuring a thread cutting design, these fasteners eliminate the need for pre-threaded holes, making them ideal for quick and efficient installation in unthreaded metal or hard plastic. The integrated hex flange ensures even pressure distribution while locking securely in place, reducing the risk of loosening under vibration, torque, or mechanical stress.
Perfect for automotive hardware, industrial machinery, and heavy-duty assembly projects, these flange lock nuts are compatible with G.M. # 11501836 and 11503432, ensuring OEM-leve.
