Our #14 ProZ™ SD T1 Hi-Lo screws with EPDM Washers are great for fastening metal to metal. These self drilling screws, also called self-tapping screws or metal-to-metal screws, have a zinc aluminum cap that stops rust. They are strong and durable, even in tough weather.
The Type #1 self-drilling point is also known as T1. This type of point eliminates the need for pre-drilling holes before inserting the screw. It has a sharp tip that can penetrate through metal surfaces, such as steel, without the need for a pilot hole. This feature simplifies installation for metal-to-metal applications.
EPDM stands for Ethylene Propylene Diene Monomer, which is a type of synthetic rubber commonly used in roofing applications. EPDM washers have a reputation for their durability and their ability to create a tight weather seal. EPDM washers on roofing screws stop leaks by sealing where the screw meets the material. This tight seal helps protect against moisture infiltration, making EPDM washers a popular choice for metal roofing projects.
The ProZ™ SD cap handles tough installation conditions. The hex head screws have a zinc aluminum coating to protect them from red rust and corrosion. This coating provides excellent durability and weather resistance, making it ideal for outdoor applications such as metal roofing.
The bronze painted hex cap on the ProZ™ SD stitch screw serves as an additional protective coating that helps corrosion resistance. The bronze color offers an attractive finish that complements a variety of sheet metal roofing colors and styles.
Hi-Lo thread refers to a type of screw thread design that combines high and low threads on the same screw. The high threads give a strong hold and secure fastening, while the low threads help to quickly screw into the material. This design makes it easy to fasten metal to metal securely and tightly. Self-drilling screws commonly feature the Hi-Lo thread design.
These #14 ProZ™ SD T1 Hi-Lo threaded stitch screws are great for drilling through steel up to 0.210" thick. They are perfect for attaching metal roofing panels, metal trim, and other metal-to-metal applications.
