Imperial Hexagonal Nut yellow Zinc Plated 1-3/4-5 Grade 8 manille Galvanized steel shackles have aThis hexagonal nut fit a threading of 1 3 4 5. It is made of yellow 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. UNC Coarse
