1. Improved Sealing The primary advantage of using rubber washers is their ability to create a watertight seal. This is invaluable in plumbing, roofing, and any situation where fluid containment is critical. By preventing leaks, these fasteners help protect materials and structures from water damage and corrosion.

4. Automotive Applications The durability and strength of these screws make them suitable for diverse automotive applications where secure joints are critical for safety and performance.

Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.
