Washers

Washers

Washers are thin, flat rings with a central hole used between fasteners like bolts and nuts to spread load, prevent surface damage, and reduce loosening from vibration. They're essential hardware for engineering students building prototypes, jigs, or assemblies.

Common Types

• Flat washers: Basic discs that distribute pressure evenly; match inner hole to bolt diameter (e.g., M4 washer fits M4 bolts).
• Spring washers: Split or wave-shaped to add tension and resist loosening under vibration or thermal expansion.
• Lock washers: Internal/external teeth that bite into surfaces for extra grip in dynamic projects.
• Standards: SAE (thinner for precision) vs. USS (thicker for heavy loads); metric follows DIN/ISO sizes.

Usage Tips

• Material: Steel (strong), stainless (corrosion-resistant), or nylon (electrical insulation).
• Sizes: Inner diameter matches bolt size; outer diameter typically 2x bolt diameter; thickness ~1/6 bolt diameter.
• Typical projects: Securing 3D prints, motor mounts, or electronics enclosures.
