3/8"-16 Heavy Hex Jam Nut, Plain

• 

The 3/8"-16 Heavy Hex Jam Nuts are thin, high-strength 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. Featuring a plain, uncoated finish, these jam nuts are ideal for applications where corrosion resistance is not required.
