Bolt and Nut vs. Tapped Hole

Bolt and Nut

A bolt passes through two or more materials and is secured with a nut on the opposite side.

Advantages:

• High strength connections
• Easy to replace damaged hardware
• Good for structural joints

Disadvantages:

• Requires access to both sides
• Can be slower to assemble

Tapped Hole

A tapped hole has internal threads cut into the material, allowing a screw to thread directly into the part.

Advantages:

• Only one-side access needed
• Clean and compact assemblies

Disadvantages:

• Threads can strip if over-tightened
• Not ideal for thin materials
