What is the Major Fastening Device Used for Permanent Fastening

Question

What is the major fastening device used for permanent fastening?
A) solder
B) screw
C) nut and bolt
D) rivet

Accepted Answer

Rivets provide a permanent, secure fastening that cannot be easily undone. They are used extensively in industries such as aerospace and automotive, as well as in construction and manufacturing. Solder is primarily used for bonding electrical components, while screws and nuts and bolts can be easily undone, making them less suitable for permanent fastening purposes.
