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
