Hex Nuts Explained: Types and Their Functions

  • click to rate

    Hex nuts are widely used fasteners that provide secure connections in construction, automotive, and industrial projects. Different types serve different needs.

    Standard Hex Nuts are the most common type and suitable for general fastening. They provide reliable strength and are available in various materials.

    Lock Hex Nuts resist loosening caused by vibration or movement. They include nylon-insert nuts for moderate conditions and all-metal nuts for high-stress environments.

    Jam Nuts are thin and used as secondary nuts to lock primary nuts, especially in tight spaces.

    Flange Hex Nuts have a flange that spreads the load, reducing material damage and eliminating washers.

    Heavy Hex Nuts are thicker and stronger than standard nuts, suitable for high-torque and load-bearing applications like structural steel and heavy machinery.

    Choosing the appropriate hex nut depends on strength requirements, environmental conditions, and vibration levels. Correct selection ensures durable, safe, and efficient fastening.
