These screws are coated with a layer of zinc to protect them from corrosion, which is particularly important in environments where moisture might be a concern. The galvanization process creates a barrier that resists the deterioration of the metal, thereby extending the lifespan of the fastener.

Hex head self-tapping bolts are characterized by their hexagonal head, which allows for easy tightening and loosening using standard hex wrenches or sockets. The self-tapping feature means that these bolts are designed to create their own threads as they are driven into materials, such as metal, wood, or plastic. This eliminates the need for a separate tapping operation, making them ideal for applications where speed and efficiency are paramount.
