About This Tool
The Fastener Calculator helps select the right screws or bolts for your boat building project. It provides recommendations for fastener type, size, and quantity based on your specific application, materials, and expected loads, ensuring a safe and robust construction.

Key Concepts:

Shear vs. Tension: Shear is a sideways load, while tension pulls a fastener straight out.
Safety Factor: How much stronger the fastener is than the expected load (4:1 is standard).
Galvanic Corrosion: Electrochemical reaction that destroys metals. Avoid mixing incompatible types.
Backing Plates: Distribute high loads on thin surfaces to prevent pull-through.
