Screw Makita F-31201 4.2x40 mm – wood/metal screw, zinc-plated

Makita screw F-31201 4.2x40 mm is a multi-purpose fastener designed for secure fixing in wood and thin metal. The 4.2 mm shank diameter and 40 mm length provide reliable holding power for joinery, framing, and light metal-to-wood connections. A zinc-plated surface improves corrosion resistance and ensures smooth driving with both cordless and corded screwdrivers or drills.

Advantages

The zinc plating reduces surface corrosion and facilitates easier insertion into timber and sheet metal while maintaining adequate shear and withdrawal strength for typical construction and repair tasks. The screw geometry is optimized for consistent thread engagement and reduced splitting in common soft and semi-hard woods. Its compatibility with standard screwdriver bits and power tools enables efficient, repeatable assembly work.

Suitable for

• Wood-to-wood connections in carpentry and furniture assembly
• Fixing into thin metal sheets where pilot holes are possible
• General construction tasks such as framing, battens and fixtures
• Repair and maintenance jobs requiring corrosion-resistant fasteners

Key specifications

• Thread diameter: 4.2 mm
• Length: 40 mm
• Material finish: zinc-plated for corrosion resistance
• Suitable for use with standard screwdriver bits and drills
• Designed for wood and thin metal fastening applications

How to use

Select an appropriate screwdriver bit or driver that matches the screw head profile and secure it in the driver chuck. For dense timber or metal fastening, pre-drill a pilot hole sized to the core diameter to reduce splitting and ensure alignment. Drive the screw straight into the material at steady speed until the head sits flush or at the desired countersink depth. Maintain controlled torque when using cordless tools to avoid overdriving or stripping the head.

Usage recommendations

For outdoor or highly humid environments consider additional protective measures such as sealed coatings or stainless alternatives; when fastening into hard or engineered woods, use a pilot hole and adjust driver torque to suit material hardness.
