Finished & Heavy Hex Jam Nuts

A jam nut is a type of lock nut about 1/2 to 2/3 the thickness of a regular hex nut. It tightens against a hex nut to create a clamping force to hold both nuts in place. Jam nut fasteners are practical for locking a hex nut when other factors prevent tightening it against the fastening surface. Because a jam nut has a thinner profile than a standard hex nut, you can also use a jam nut in applications where a standard nut cannot fit.

Specifications of Finished Hex Jam Nuts

Brazos Fasteners distributes finished hex jam nuts and heavy hex jam nuts made from:

  • 304 and 316 stainless steel
  • Zinc plated
  • Mechanically galvanized
  • Teflon blue
  • Brass
  • Silicon bronze

Steel jam nuts are often plated to resist corrosion.

We provide jam nuts in various sizes. Nominal thread diameters typically range from 1/4″ to 2 1/2″.

Applications of Heavy Hex Jam Nuts

Jam nut fasteners may benefit you when:

  • Tightening the nut against a soft material may cause damage.
  • The bolt head is behind an enclosure so you cannot access it for tightening.
  • The bolt is headless.
  • Vibration or external force can loosen a bolt-and-nut connection.

Jam nuts are useful in the energy industry to secure pipes or valves. They are also used in the automotive, heavy truck, agriculture, heavy equipment, railroad, and mining industries.
