Key Features & Benefits
/1
Harpoon thread = stronger grip in thin steel
The catalogue highlights a harpoon thread profile with sharper angles than a normal thread, making TRUSSTAPP® one of the most effective light gauge steel screws and self tapping screws available.
- Improve bite and engagement as reliable steel to steel fasteners
- Increase resistance to pull-out in structural fasteners applications
- Support easier installation and time savings in light gauge work
- Improve bite and engagement as reliable steel to steel fasteners
- Increase resistance to pull-out in structural fasteners applications
- Support easier installation and time savings in light gauge work
/2
LEVIN® drill point for quick drilling + tight engagement
The LEVIN® drill point is designed to drill efficiently and reduce common installation problems like slipping or stripping, especially important in repetitive frame assembly using self-drilling screws for pre-engineered building fasteners projects.
/3
Hex washer flange head for stable driving
The hex washer flange head provides positive tool engagement and stable seating, supporting consistent fastening on site, a key advantage for self drilling screws and structural fasteners used in high-volume truss assembly.
Quality, Testing & Assurance
TRUSSTAPP® is part of a purpose-built fastener range for construction fastening. As a precision-engineered self drilling screw and steel to steel fastener, its thread + point + head design is intended to deliver:
Faster assembly cycles forpre-engineered building fasteners installations
Higher holding confidence in light gauge steel — the hallmark of reliable light gauge steel screws
Consistent engagement for repetitive truss/frame fastening using structural fasteners
How to Select the Right TRUSSTAPP® Screw?
Identify the structural application – Choose the TRUSSTAPP® screw based on its use in trusses, purlins, or heavy steel connections, matching the right structural fasteners or pre-engineered building fasteners to the job.
Check steel thickness – Select the drill point and screw length to suit light or heavy gauge steel, ensuring your light gauge steel screws or self drilling screws perform correctly.
Evaluate load & strength needs – Ensure the screw meets required tensile and shear load capacity for structural stability when specifying steel to steel fasteners and self tapping screws.
Consider exposure conditions – Opt for corrosion-resistant coatings and suitable head types for long-term performance, especially for structural fasteners in outdoor or industrial settings.
