Screw/Bolt Fischer 670346

The Fischer 670346 screw/bolt is a zinc-finished fastener designed for reliable wood connections. Manufactured by FISCHER, this hardware item combines corrosion-resistant zinc plating with a geometry suitable for timber assemblies. The product is supplied in packaging with compact outer dimensions for convenient storage and transport, and its weight reflects a standard quantity suitable for small to medium fastening tasks.

Advantages

Zinc plating provides improved resistance to rust and surface wear compared with untreated steel, extending service life in interior and sheltered exterior wood applications. The bolt geometry ensures consistent engagement in wooden substrates, reducing splitting and improving clamping performance when paired with appropriate pre-drilled holes or pilot threads. The compact packaging makes handling and storage straightforward for professionals and DIY users.

Suitable for

• Securing wooden beams and joists
• Furniture assembly and repair
• Mounting wooden fixtures and brackets
• General carpentry and joinery tasks

Key specifications

• Material finish: zinc-plated steel
• Intended substrate: wood
• Package weight: 1.36 kg
• Package outer dimensions: 230 mm (width) × 90 mm (height)
• Fastener type: screw/bolt for mechanical wood fastening

How to use

Choose an appropriate diameter and length of pilot hole or pre-drill according to the wood density and the bolt diameter to avoid splitting. Position the bolt and drive it with a compatible driver or wrench until the head seats firmly against the surface; do not overtighten to prevent crushing the wood fibers. For load-bearing connections, use washers and nuts as required and check alignment before final tightening.

Usage recommendations

For exterior or high-humidity environments, consider additional corrosion protection or select stainless fasteners. When fastening into hardwoods, increase pilot hole size slightly to reduce driving torque. Always follow structural guidelines and local building codes for load-bearing installations.
