Modified Truss Head Self-Drilling Screw
Modified Truss Self-Drilling Screw, Also known as Washer head drill nail, is a new type of high-efficiency riveting fastener; drill screws are named drill self-drilling self-tapping screws because of the drill tail, also known as self-drilling self-tapping screws, drill screws, drill wires, drill nails, self-drilling screws, drill self-tapping self-drilling screws, etc. The tail of the drill screw has a self-drilling head in the shape of a drill tail or a pointed tail. When the drill screw is used to rivet the connected parts, the surface and interior of the connected parts do not require auxiliary processing. The drill screw can directly drill, tap, and lock the setting material and base material in one go. It can quickly and automatically drill and directly tighten and fix; the construction efficiency of the drill screw is extremely high; it saves construction time to the maximum extent, improves engineering construction efficiency, and improves economic benefits. The connected parts riveted with the drill screw have strong bonding force, high preload force, and high stability of the connected parts. When selecting the drill screw, it is necessary to select the drill screw of the appropriate model, material, and size according to the material and thickness of the connected parts to be fixed.
Product Name
Modified Truss Head Self-Drilling Screw
(English: Modified Truss Head Self-Drilling Screw)
Product Description
Modified Truss Head Self-Drilling Screw is an efficient fastener designed for metal-to-metal connections, suitable for multiple fields such as construction, mechanical manufacturing, and heating, ventilation, and air conditioning (HVAC) systems. This screw combines self-drilling function, low-profile truss head design, and galvanized anti-corrosion properties. It can quickly penetrate and fix metal materials without pre-drilling, significantly improving installation efficiency. It is made of high-strength steel, the surface is galvanized, and has excellent corrosion resistance, suitable for various harsh environments indoors and outdoors. Whether it is steel structure construction, metal roof installation or equipment assembly, this screw can provide a stable and reliable connection solution.
Product Features
- Self-drilling tip: Equipped with #2 or #3 drill tip, it can easily penetrate metal materials with a thickness of 0.035 inches to 0.100 inches, and drilling and fastening are completed in one step.
- Improved truss head: Low profile design, wider head, increased bearing area, reduced pressure loss on thin metal, and smooth and beautiful appearance after installation.
- Phillips drive: Cross slot design, compatible with most power tools and manual screwdrivers, easy to install and operate.
- Galvanized treatment: The surface zinc coating effectively prevents rust and prolongs service life, suitable for wet or outdoor use.
- Multiple specifications: Provide multiple diameters such as #8, #10, #12, and 1/2 inch to 3 inches to meet different connection needs.
- High-strength material: C1022A steel is selected, which is heat-treated, high hardness and fatigue-resistant to ensure long-term use without loosening.
Product advantages
- Efficient installation: The self-drilling design eliminates the pre-drilling step, which is particularly suitable for large-scale construction, saving time and labor costs.
- Wide application: Suitable for a variety of metal connection scenarios such as steel structures, metal roofs, wall panels, HVAC pipes, etc.
- Safe and beautiful: The low-profile head reduces the risk of protrusion, ensures a flat installation surface, and improves the overall aesthetics.
- Durable and environmentally friendly: The galvanized layer enhances corrosion resistance, meets environmental standards, and reduces subsequent maintenance costs.
- Flexible choice: A variety of packaging specifications (1 pound, 5 pound box or 20 pound barrel) are available to meet the purchasing needs of individuals and enterprises.
