Nut (hardware)

A nut is a type of hardware. It is a small, often hexagonal piece of metal, with a hole with internal screw thread, to be fitted onto a bolt, or cap screw, which is inserted through holes of two or more objects, to attach these objects to each other.

Nuts are graded with ratings compatible with cap screws; for example, a grade 8 nut will be able to support the rated torque and clamp load of a grade 8 cap screw.

    • polymer insert
    • oval lock
  • T-nut
