Product
The SPAX-RA Wirox T-STAR plus full thread cylindrical head screw Ø7.5x40mm is designed for special applications such as mounting frames without plugs. It is ideal for direct installation into substrates after drilling a 6.5 mm hole, providing a strong and efficient fixing solution for wood, metal, and masonry structures.
Specifications
- Manufactured from zinc-plated steel with a WIROX coating for enhanced corrosion resistance
- Features a full thread and a cylindrical head for flush mounting and minimal visibility in wood construction
- Equipped with a T-STAR plus (hexalobular internal) drive for optimal force transmission and reduced bit slippage
- Diameter: 7.5 mm; Length: 40 mm; Supplied in boxes of 100
- Suitable for heavy-duty connections, enables high tensile force absorption, and complies with ETA certification requirements
Usage
This screw is intended for direct installation in window and door frames or chassis without the need for additional plugs. After drilling a pilot hole of 6.5 mm using an SDS type drill bit, the screw is driven directly into the substrate using a T-STAR plus bit, ensuring fast and secure anchoring. Its cylindrical head allows for countersunk, virtually invisible connections, especially in wood or metal frameworks.
