|
Nuts |
Bolts |
|
|
Function |
Nuts complement bolts by providing the necessary tension. |
Bolts are used to hold materials together by passing through pre-drilled holes and being fastened with a nut on the other side. |
|
Structure |
Nuts have internal threads and are typically hexagonal to fit a wrench. |
Bolts have external threads and a head for applying torque |
|
Application |
Nuts are paired with bolts to achieve this secure fastening. |
Bolts are used where parts need to be held together strongly and can be tightened with tools. |
