Washers

Washers are thin, flat discs that are used in conjunction with fasteners (like bolts and screws) to distribute load, reduce friction, prevent loosening, and protect surfaces. Here’s a breakdown of the key features and specifications of washers:

  1. Load Distribution: Washers help spread the load of a fastener over a larger surface area, reducing the risk of damage to the material being fastened.
  2. Friction Reduction: They minimize friction between surfaces, making it easier to tighten fasteners and reducing wear over time.
  3. Vibration Resistance: Certain types of washers (like lock washers) are designed to prevent fasteners from loosening due to vibrations.
  4. Surface Protection: Washers can protect the surfaces of materials from damage caused by the fastener head or nut.
  5. Versatility: Available in various shapes, sizes, and materials to suit different applications.
  1. Types: Common types include flat washers, lock washers (split, tooth, etc.), fender washers, and rubber washers, each serving specific functions.
  2. Material: Made from various materials such as steel, stainless steel, plastic, or rubber, depending on the application requirements and environmental conditions.
  3. Diameter: Available in a range of inner and outer diameters to fit different fastener sizes and application needs.
  4. Thickness: Washers come in different thicknesses, affecting load distribution and compression characteristics.
  5. Finish Options: Often available in various finishes (e.g., zinc plated, galvanized, or coated) to provide corrosion resistance and aesthetic appeal.
