Conclusion

Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.
