Ruuvit Fischer 670023 12 mm 200 kpl

Fischer 670023 12 mm screws are precision-made fastening elements designed for wood applications. Each screw has a total length of 12 mm with a threaded section of 8 mm and a nominal diameter of 3 mm. Manufactured from durable metal, this pack contains 200 pieces, offering a reliable supply for both single projects and ongoing work. The screws feature a design intended to provide secure holding power and dimensional consistency across the batch.

Advantages

The metal construction provides corrosion resistance and mechanical strength suitable for typical indoor carpentry and joinery. Consistent thread geometry and a defined threaded length enable predictable engagement in wooden substrates while reducing splitting risk when used with appropriate pilot holes. A 3 mm diameter balances shear strength and ease of insertion for common wood densities.

Suitable for

• Indoor wood joinery and furniture assembly
• Fixing thin wooden panels and trim
• DIY home improvement projects involving timber
• Small carpentry repairs and fittings

Key specifications

• Overall length: 12 mm
• Threaded length: 8 mm
• Nominal diameter: 3 mm
• Material: metal (durable, corrosion-resistant finish)
• Quantity per pack: 200 pieces
• Intended substrate: wood

How to use

Select an appropriate screwdriver or power driver bit that matches the screw head profile. If working with hardwood or near edges, drill a pilot hole sized to the screw root diameter to reduce splitting. Position the screw perpendicular to the work surface and drive at moderate speed, applying steady pressure until the head is flush or slightly countersunk as required. For repeated fastening tasks, use a driver with adjustable torque to prevent overdriving.

Recommendations

Store screws in a dry environment to maintain finish and performance. For outdoor or high-moisture applications, use screws and fasteners specified for exterior use or apply supplemental corrosion protection. When fastening thin or delicate panels, test on a scrap piece to confirm pilot hole size and driving depth.
