Screw Fischer 670407

Fischer 670407 screws are metal wood screws designed for reliable fastening in a variety of woodworking applications. Each screw has an overall length of 100 mm, with a 6 cm threaded portion and a 5 mm thread diameter. The pack contains 100 screws, offering a practical quantity for large or multiple projects where consistent performance and secure joints are required.

Advantages

These metal wood screws provide durable mechanical connection and good resistance to shear and pull-out forces when used in appropriate timber and assembly contexts. The 5 mm thread diameter balances holding strength with ease of insertion into predrilled holes or pilot points. A 60 mm thread length allows for deep engagement in thicker workpieces, reducing movement and improving stability of assemblies.

Suitable for

• General carpentry and joinery work
• Furniture assembly and repair
• Decking and exterior wood structures (with appropriate corrosion protection)
• Framing, substructures and timber connections

Key specifications

• Material: metal (steel)
• Overall length: 100 mm
• Thread length: 60 mm
• Thread diameter: 5 mm
• Pack quantity: 100 pieces
• Intended application: wood fastening

How to use

For best results, select a screw length and diameter appropriate for the workpiece thickness and type of wood. Pre-drill a pilot hole sized for the screw core in hard woods to prevent splitting; in softer woods, a smaller pilot hole or direct driving may be used depending on the assembly. Use a compatible screwdriver bit or drill/driver with torque control to drive the screw until the head sits flush or to the required depth. For outdoor or moisture-exposed applications, ensure the screws and surrounding materials have suitable corrosion protection.

Usage recommendations

Store screws in a dry environment to prevent surface corrosion. When fastening load-bearing joints, follow structural guidelines and consider using washers or additional reinforcement if required. Match screw type and finish to the environmental conditions and timber species to ensure long-term performance.
