Nuts pair with bolts, cap screws, studs and threaded rod in every kind of assembly. This section covers finished hex nuts, heavy hex nuts, jam nuts, nylon insert lock nuts, all-metal prevailing torque lock nuts, serrated flange nuts, wing nuts, coupling nuts, acorn cap nuts, square nuts and keps nuts. Sizes run through common inch threads in UNC and UNF and metric threads, in steel by grade, stainless steel and brass.

What to check before you order

• Thread size and pitch. The nut must match the bolt exactly. A 3/8"-16 nut will not fit a 3/8"-24 bolt.
• Grade. Use a nut of equal or higher grade than the bolt. A Grade 8 bolt needs a Grade 8 nut to carry its rated load.
• Locking method. Nylon insert lock nuts resist loosening from vibration but should be kept below their temperature limit. All-metal lock nuts are used where heat would damage nylon.
• Height. Jam nuts are thinner and are used to lock another nut or set a position. They are not meant to carry full load by themselves.
• Finish. Galvanized bolts need nuts tapped oversize for the coating.

Common questions

Can I reuse a nylon insert lock nut?

They lose some locking ability each time they are removed. For critical joints, replace them rather than reuse them.
