Imperial Hexagonal Nut black Zinc Plated Fine Thread 2-1/2-12 Grade 8 unc these are designed for through-holeThis hexagonal nut fit a threading of 2 1 2 12. It is made of black zinc plated and thus provide medium resistance to corrosion in dry environments and low resistance in wet environments, but Yellow Zinc provide a higher corrosion resistance than regular zinc. The Grade 8 increases its strength against the pressure and has a tensile strength and hardness of 150,000 psi Rockwell C33. Furthermore, it features a shear strength of 90,000 psi. UNF Fine
