FISCHER 300 mm screws are metal wood screws designed for deep, durable fastening in timber and thick wooden constructions. Each pack contains 50 screws with a total length of 300 mm, a thread length of 70 mm and a 6 mm diameter, providing robust mechanical holding where long penetration is required. The screws are suitable for connections in structural and non-structural wooden elements, offering consistent geometry for predictable performance during driving and load-bearing.
The full-length metal shank and defined thread geometry ensure secure engagement in wood and laminated timber. A 6 mm diameter combined with a 70 mm threaded portion gives a balance between shear strength and ease of insertion. The 300 mm overall length enables fastening through thick boards or multiple layers without the need for additional connectors. Consistent dimensions across the 50-piece pack aid planning and reduce variability on site.
Pre-drill a pilot hole appropriate for a 6 mm wood screw to reduce splitting, especially near edges or in hardwoods. Position the screw and drive with a compatible bit and sufficient torque; use a cordless drill or impact driver set to a controlled speed to avoid over-torquing. Ensure the threaded section fully engages the receiving material while the smooth shank passes through the first element to allow clamping. Check alignment and clearance before final tightening.
Use corrosion-resistant fasteners or appropriate surface treatments when installing outdoors or in humid environments. Select pilot hole diameter based on wood density—larger holes for hardwoods, smaller for softwoods—and consider pre-drilling clearance holes in the outer member for optimal clamping. Store screws in a dry place to prevent surface corrosion before installation.
