Screw FISCHER 670665 – metal wood screw, 45 mm length, 4.5 mm diameter, pack of 50

FISCHER metal wood screw, 45 mm length and 4.5 mm diameter, supplied in a pack of 50, is designed for reliable fastening in timber and common woodworking applications. The screw features a 40 mm effective thread length that secures components while the unthreaded shank portion allows tight clamping of workpieces. Its dimensions make it suitable for furniture assembly, carpentry tasks and general structural joins where a medium-length wood screw is required.

Advantages

The screw provides consistent thread engagement and controlled insertion torque for repeatable results in soft and hardwoods. A precisely formed thread profile reduces splitting risk when predrilling is used, and the combination of thread length and shank ensures good pull-out resistance and clamping force. Supplied in a pack of 50, these screws simplify inventory management for small projects and professional jobs where multiple fasteners are needed.

Suitable for

• Furniture assembly and repair
• General carpentry and joinery
• Fixing fittings, brackets and hardware to wooden substrates
• Interior wood structural joins and paneling

Key specifications

• Overall length: 45 mm
• Thread length: 40 mm
• Thread diameter: 4.5 mm
• Material: metal suitable for wood applications
• Pack quantity: 50 pieces

How to use

Select an appropriate screw head driver or bit that matches the screw head. For best results, choose a pilot hole diameter appropriate to the wood species and screw diameter to minimise splitting and ease insertion. Insert the screw straight into the pilot hole and drive until the head sits flush or slightly countersunk with the workpiece surface, taking care not to over-torque and damage the screw or material. When joining thicker sections or where greater clamping is needed, ensure full thread engagement across the joined parts.

Usage recommendations

For hardwoods, predrill pilot holes and consider using a countersink for a flush finish. For exterior or moisture-exposed applications, use appropriate corrosion-resistant coatings or stainless fasteners. Store screws in a dry place to avoid surface corrosion and keep the original packaging to maintain organisation on site.
