Parafusos Fischer 670239 40 mm 200 unid.

Fischer 670239 screws are 40 mm wood screws supplied in a pack of 200 pieces. Each screw features a 35 mm thread length and a design optimized for reliable fixing in timber and wood-based materials. The screws are intended for general utility applications where durable joints and predictable performance are required.

Advantages

These Fischer wood screws combine a consistent thread profile with a full-length point to ensure straightforward driving into wood without frequent pre-drilling for softer timber. The 40 mm overall length with 35 mm threaded portion provides secure engagement while allowing a short unthreaded shank when needed. Supplied in a bulk pack of 200, they offer cost-effective quantity for larger projects and professional use.

Key specifications

• Length: 40 mm
• Thread length: 35 mm
• Pack quantity: 200 pieces
• Intended material: wood and wood-based materials
• Application type: general-purpose wood fixing

How to use

Select an appropriate screwdriver or drill/driver bit that matches the screw head. For hard or brittle hardwoods, pre-drilling a pilot hole with a drill bit slightly smaller than the core diameter of the screw reduces splitting risk. Drive the screw until the head sits flush or to the required depth, avoiding over-tightening which can strip the thread or damage the workpiece. Use consistent driving speed and pressure for best results.

Recommendations

For structural joins or exposed outdoor applications, verify compatibility with the material and environmental conditions; use appropriate corrosion-resistant fasteners if needed. Store the screws in a dry place to preserve condition and ease of handling during installation.

Fischer 670239 40 mm wood screws are a practical choice when reliable, general-purpose wood fasteners in larger quantity are required for construction, renovation, or workshop use.
