DaHe Fastener offers a wide variety of screws for the metal building and metal roofing industry. Our screws are designed and meet strict specifications to withstand the rigors of today’s construction. From self-drilling and flange head to self-tappers screws, we have everything you need for your next project.

Our metal building screws can be coated in Ruspert, our high-grade metal surface technology that prevents corrosion.Ruspert, consists of three layers: a metallic zinc later, a high grade anti-corrosion chemical conversion film, and a baked ceramic surface coating.

The layers are bonded together through chemical reactions, which results in a rigid combination of the coating films, providing a superior rust resistance.

The best way to avoid corrosion is to ensure you are using the right materials and coatings for the job. You should also make sure the fasteners are being stored properly on the jobsite, and are installed correctly. If you have any questions, always refer to your project engineer and follow the proper standards for the project.

Quality is everything when it comes to screws and other types of fasteners. Fasteners are the backbone of your building, so it’s critical not to cut corners and use low quality screws in your project. DaHe Fastener takes special measures to ensure metal screw quality, including 1000 hour salt spray tests and pull out/pull over testing.

In addition to our screws being designed to meet the harshness of the environment, our expert sales team can make product recommendations for your project. From 1000 hour salt spray testing to pull-out and pull-over testing, we will partner with you to provide a successful and stress-free job.

DaHe Fastener has the ability to match all building manufacturing colors. With our in-house powder coat facility, we can provide an attractive durable finish unmatched in the industry. contact our sales team to discuss how we can create custom colors.
