Tornillo para madera FISCHER PowerFast II 10,0x100 mm Cabeza plana TX galvanizado

FISCHER PowerFast II 10.0x100 mm flat head TX galvanized is a wood construction screw designed for secure joining of timber components. The screw features a countersunk (flat) head with TX (Torx) drive and a fully threaded shank, offering strong grip and reliable load transfer in wooden connections. Galvanized surface treatment increases corrosion resistance, making the fastener suitable for interior and exterior applications where moderate environmental protection is required.

Advantages

The flat head design allows the screw to sit flush with workpiece surfaces for neat finishes and to reduce interference with subsequent layers. TX drive provides improved torque transfer and lower cam-out compared to traditional Phillips drives, enabling faster and more controlled installation. Full-thread profile and optimized thread geometry ensure good pull-out resistance and even clamping force across joined timber elements. Galvanized coating offers protection against rust in environments with occasional moisture exposure.

Suitable for

• Structural wood-to-wood connections in carpentry and timber framing
• Fixing joists, beams and battens
• Mounting wooden decking substructures and outdoor timber assemblies
• Interior furniture assembly where countersunk finish is required

Key specifications

• Diameter: 10.0 mm
• Length: 100 mm
• Head type: flat (countersunk)
• Drive type: TX (Torx)
• Threading: fully threaded shank
• Surface finish: galvanized for corrosion resistance
• Material: high-strength steel suitable for structural timber fastenings

How to use

Select an appropriate drill or pilot hole size when working with hardwoods or highly stressed connections to prevent splitting. Use a TX bit matching the screw drive and a power tool with adjustable torque to control insertion. Position the screw and drive at a right angle to the timber surface and apply steady pressure while fastening until the flat head is flush with the wood. For exterior applications, ensure contact surfaces are free from debris and consider applying compatible edge protection or sealant for prolonged corrosion resistance.

Recommendations

For best performance in structural applications, follow applicable building codes and fastening guidelines for spacing, edge distances and predrilling. When using in treated timber or in persistently damp environments, evaluate the corrosion class requirements and, if necessary, choose a stainless or higher-grade coated fastener.
