Beginner's Guide to Fasteners: Nuts, Bolts, Washers Explained
New to fasteners? This comprehensive guide explains the basics of nuts, bolts, and washers—helping you understand what each component does and when to use it.
1. Understanding Bolts
Bolts are externally threaded fasteners designed to be used with nuts. They come in various grades (indicating strength), head styles, and thread patterns. Common types include hex bolts, carriage bolts, and eye bolts, each serving specific purposes.
2. Nut Fundamentals
Nuts are internally threaded fasteners that pair with bolts. Hex nuts are most common, but lock nuts prevent loosening, wing nuts allow hand-tightening, and coupling nuts join threaded rods. Always match nut thread to bolt thread.
3. The Role of Washers
Washers serve multiple purposes: distributing load over a larger area, preventing surface damage, providing spacing, and preventing loosening. Flat washers are most common, while lock washers and spring washers prevent rotation.
4. Thread Compatibility
Ensure threads match between bolts and nuts. Metric and imperial threads are not interchangeable. Coarse threads are standard; fine threads provide more precise adjustment and better resistance to vibration loosening.
5. Material Selection
Stainless steel resists corrosion, galvanized steel offers good outdoor performance, and nylon provides electrical insulation. Match material to your environment for longest service life.
