About Nuts, Materials, and Finishes
Types of Nuts
Hex Nuts are the most common nuts for general fastening applications.

| Hex | Thin Hex | Extra-Wide Hex | Extra-Wide Thin Hex | High Hex |
Locknuts have a locking feature to resist loosening under vibration.
Flange nuts distribute holding pressure and reduce stress where the nut meets the material surface. Their wide base eliminates the need for a separate washer.
Cap nuts cover and protect threads while adding a finished appearance.
Square nuts have large sides, which makes them easier to grip with a wrench and keeps them from rotating in channels and square holes.
Thumb and wing nuts can be tightened or loosened by hand. They’re often used in applications that require frequent adjustments.
Quick-threading nuts slide smoothly onto threads for quick installation and easy adjustments.
Coupling nuts are used to connect or extend threaded rod. They’re about three-times taller than standard hex nuts.
Tamper-resistant nuts have hard-to-grip uncommon drive styles to reduce the risk of theft and tampering.
Press-fit nuts add threads to thin metal or plastic panels. Install using an arbor press or similar pressure tool.
Weld nuts add threads to metal surfaces.
Comparing Materials by Strength
Comparing Coatings and Finishes by Corrosion Resistance
Choosing a Compatible Nut Grade
Match your bolt, screw or threaded rod with a comparable strength nut.
Understanding Thread Size
Inch sizes are specified by the diameter of the opening and threads per inch. For those with a diameter smaller than 1/4", diameter is indicated by a number (e.g., #1 or No. 1).
Metric sizes are specified by the diameter of the opening and pitch.
