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, designed to:
- Improve bite and engagement
- Increase resistance to pull-out
- Support easier installation and time savings in light gauge work
- Improve bite and engagement
- Increase resistance to pull-out
- 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.
/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.
Quality, Testing & Assurance
TRUSSTAPP® is part of a purpose-built fastener range for construction fastening. Its thread + point + head design is intended to deliver:
Faster assembly cycles
Higher holding confidence in light gauge steel
Consistent engagement for repetitive truss/frame fastening
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.
Check steel thickness – Select the appropriate drill point and screw length to suit light or heavy gauge steel sections.
Evaluate load & strength needs – Ensure the screw meets the required tensile and shear load capacity for structural stability.
Consider exposure conditions – Opt for corrosion-resistant coatings and suitable head types for long-term performance in harsh environments.
