M12-1.75 Hex Jam Nut, CL4, Zinc

• 

The M12-1.75 Hex Jam Nuts are thin, high-strength metric fasteners designed for locking applications. Their reduced thickness allows them to be tightened against a standard nut to prevent loosening, while the heavy design provides increased strength. They are heavily utilized in the automotive industry for machinery and equipment where space is limited and vibrations are common. The nuts are plated with zinc for moderate corrosion resistance without compromising strength.
