Screw Fischer 670376 50 mm

Fischer 670376 50 mm screws are metal fastening elements designed for wood applications. Each pack contains 200 screws with a total length of 50 mm, a thread length of 30 mm and a 5 mm diameter. The screws provide reliable mechanical connection for carpentry, joinery and general wood construction tasks where a strong hold and consistent thread engagement are required.

Advantages

These metal wood screws combine a long shank and substantial thread length to deliver secure anchoring in soft and hard woods. The 5 mm diameter balances shear strength and ease of driving, while the 50 mm overall length allows penetration sufficient for most board-to-board and fixture-to-wood joints. Supplied in packs of 200, they are suitable for larger projects or repeated use, reducing the need for frequent restocking.

Suitable for (tasks / use cases)

• Securing boards, battens and planks in carpentry and timber framing
• Assembling furniture components and shelving fixed to wooden supports
• Mounting fixtures, brackets and fittings to wooden substrates
• General repairs and renovation work where wood-to-wood fastening is needed

Key specifications

How to use

Select an appropriate screwdriver or drill driver bit that matches the screw head. Pre-drilling a pilot hole is recommended for hardwoods or near edges to prevent splitting; choose a drill bit slightly smaller than the screw core diameter. Position the screw perpendicular to the workpiece and drive at moderate speed until the head sits flush or at the required depth. When joining thin materials or when countersinking is required, use a countersink bit before inserting the screw.

Usage recommendations

For optimal performance, use these screws with untreated or treated wood as intended. Avoid over-torquing to prevent head stripping or material damage. Store the screws in a dry environment to minimize surface corrosion if used in exposed outdoor conditions; consider additional corrosion protection when required by the application.
