Durable #4 (2.9mm) truss head self-drilling screws with Phillips drive, ideal for secure fastening in various materials without pre-drilling. Perfect for agricultural and general construction applications.
Agricart presents high-quality #4 (2.9mm) Truss Head Phillips Drive Self-Drilling Screws, engineered for efficiency and reliability in a wide range of fastening tasks. These screws feature a distinctive truss head, which provides a large bearing surface for a secure hold and a low-profile finish. The Phillips drive ensures positive bit engagement, reducing cam-out and making installation smoother and faster. Designed with a self-drilling point, these screws eliminate the need for pre-drilling in many applications, saving time and effort on the job site. They are constructed from robust materials, offering excellent corrosion resistance and durability, making them suitable for both indoor and outdoor use in agricultural settings, metal fabrication, and general construction projects. Available in various lengths to meet specific project requirements.
Select the appropriate screw length for your material thickness. Use a Phillips head screwdriver or drill bit. Apply steady, even pressure while driving the screw to ensure proper engagement and prevent stripping. Do not overtighten. For best results, ensure the material is clean and free of obstructions. Always wear appropriate safety gear, including eye protection.
Eliminates pre-drilling, saving time and labor. Large truss head provides excellent clamping force and a finished look. Phillips drive reduces cam-out for easier installation. Durable construction ensures long-lasting performance. Versatile for various materials including metal, wood, and plastic. Corrosion-resistant finish for extended life.
Not suitable for all materials; test on a scrap piece first. Overtightening can strip the threads or damage the material. Always use the correct size Phillips bit to prevent cam-out. Keep out of reach of children. Sharp points can cause injury.
Consider the material you are fastening and its thickness to choose the correct screw length. For outdoor or high-moisture environments, opt for screws with enhanced corrosion resistance. Check the quantity needed for your project to ensure you order enough. Agricart offers various pack sizes to suit your needs.

- What is a truss head screw?
- A truss head screw has a wide, low-profile domed head with a large bearing surface. This design provides a strong clamping force and a clean, finished appearance, making it ideal for attaching thin materials or where a larger surface area is desired for stability.
- Can these screws be used in metal?
- Yes, these self-drilling screws are specifically designed to drill their own pilot hole and tap threads in various metals, including sheet metal, without the need for pre-drilling. Always ensure the material thickness is appropriate for the screw's drilling capacity.
- What is the advantage of a Phillips drive?
- The Phillips drive provides four points of contact, allowing for better torque transmission and reducing the likelihood of the driver bit slipping out (cam-out) compared to a slotted drive. This makes installation more efficient and less prone to damage to the screw head.
- Are these screws corrosion resistant?
- Yes, these screws typically feature a galvanized or other protective coating to enhance their corrosion resistance, making them suitable for use in environments where moisture or other corrosive elements might be present, such as in agricultural applications.
- What does '#4 (2.9mm)' signify?
- '#4' refers to the screw's gauge or nominal diameter according to a standard sizing system, while '2.9mm' is the approximate metric equivalent of that diameter. Both indicate the thickness of the screw's shank.
