SWENN SWHT3P5.5xL Self-Drilling Screw

SWENN Hex Head self-drilling screws with a high thread design are designed to drill and tap in metal-to-metal fixing applications. Their typical applications include fastening in roofing, cladding, insulated panels, and sandwich panels. The high thread provides secured fastening strength.

Application Range

  • Recommended to use for fastening of sandwich panel to steel substructure.

  • Features

  • SWENN high-thread screws is designed for double fixing mechanism top and bottom layers of the panel.

  • Offers secure mechanism for walkthrough movement.

  • Special design prevents the screw from drilling and tapping simultaneously to avoid any screw damage.

Carbon Steel Coatings


UltraDuro:

UltraDuro coating offers superior protection against corrosion with its combination of metallic zinc+tin layers, high-grade anti-corrosion coating, and a special chemical conversion film. It undergoes a diffusive-adhesion treatment to ensure excellent as per ASTM B117, 1000 hrs min.

GRI Coating:

The GRI Tech coating has three layers that securely bond to the ceramic topcoat and metallic zinc, providing protection to the metal substrate. It eliminates contact corrosion problems with other metals (Bimetallic corrosion) and maintains the integrity of the zinc coating on screws even in wet and dry conditions. Salt Spray Test has been conducted as per ASTM B117, 1000 hrs min.
