While not fasteners in the traditional sense, washers are often used in conjunction with bolts, nuts, and screws to improve their performance. Washers distribute the load of the fastener over a larger surface area, helping to prevent damage to the material being fastened and reducing the risk of loosening due to vibration. There are several types of washers, including flat washers, lock washers, and fender washers, each serving specific functions in various applications.

The chemistry behind these substances is complex yet fascinating. Epoxy resins, for example, are composed of a hardener and a resin, which when combined, undergo a chemical reaction resulting in a rigid, durable bond Epoxy resins, for example, are composed of a hardener and a resin, which when combined, undergo a chemical reaction resulting in a rigid, durable bond Epoxy resins, for example, are composed of a hardener and a resin, which when combined, undergo a chemical reaction resulting in a rigid, durable bond Epoxy resins, for example, are composed of a hardener and a resin, which when combined, undergo a chemical reaction resulting in a rigid, durable bondanchor fastener chemical. Urethane adhesives, on the other hand, are known for their flexibility and excellent impact resistance. The selection of the right chemical anchor depends on factors such as the type of substrate, load requirements, environmental conditions, and the expected service life of the structure.
