Bolts come in various types, each suited for specific applications. The main types include:
- Hex Bolts: These are often applied in building and fixing work because they offer flexibility and robustness.
- Carriage bolts: They have a round head and square neck, good for fastening wood to wood or metal to wood.
- Lag Bolts: Heavy-duty bolts are used for wood applications, providing strong holding power.
- Machine Bolts: Used in machinery and equipment, often with a square or hex head.
- Anchor Bolts: Designed to attach structures to concrete, they are used in construction and infrastructure projects.
When choosing a bolt, consider:
- Material: Match the bolt material (for example, stainless steel, carbon steel, or brass) to environmental conditions and needed strength.
- Thread Type: Ensure the thread type (coarse or fine) is compatible with the nut or tapped hole.
- Length and Diameter: Choose dimensions that align with the thickness of the materials you are joining together and give enough strength.
- Coating: If needed, select bolts with protective coatings (e.g., galvanized, zinc-plated) for corrosion resistance.
