Fischer 670469 csavar 240 mm 50 darab

Fischer 670469 screws are stainless steel fasteners with a length of 240 mm and a nominal diameter of 6 mm, supplied in a pack of 50. Intended primarily for use in wood, each screw has an approximate thread length of 70 mm and a head and shaft geometry designed to provide secure mechanical connections in timber assemblies. The corrosion-resistant stainless steel construction makes these screws suitable for indoor and outdoor applications where moisture resistance is required.

Advantages

Stainless steel construction ensures increased corrosion resistance compared with standard carbon steel screws. The 240 mm length and 6 mm diameter provide high pull-out strength and good shear performance in solid wood elements. Supplied in a bulk pack of 50, these screws offer consistent dimensions and thread form for repeatable fastening results across multiple workpieces. The defined thread length concentrates holding power where needed while allowing for effective clamping of joined parts.

Suitable for

• Securing structural and non-structural timber connections
• Exterior wooden constructions where corrosion resistance is required
• Decking, pergolas, garden structures and wooden facades
• Heavy-duty DIY projects and professional carpentry

Key specifications

• Material: stainless steel
• Length: 240 mm
• Nominal diameter: 6 mm
• Thread length: approximately 70 mm
• Pack quantity: 50 pieces

How to use

Select an appropriate pilot hole diameter and depth for the 6 mm nominal diameter screw to reduce the risk of wood splitting, especially near edges or in hard woods. Use a compatible driver bit and a drill or impact driver set to a controlled speed and torque to drive the screw until the head is flush or slightly countersunk, depending on the joint design. For repetitive assembly, a depth stop or a collar on the bit helps maintain consistent insertion depth and prevents overdriving.

Recommendations

For outdoor use, ensure mating materials and any adjacent metal components are compatible with stainless steel to avoid galvanic corrosion. Pre-drilling is recommended for dense hardwoods and near edges. When used in structural applications, follow applicable building codes and load requirements and consider additional corrosion protection or sealing for prolonged exposure in aggressive environments.
