Csavar Fischer 670006 20 mm 200 db

Fischer 670006 screws are metal wood screws with a 20 mm overall length and a thread length of 16 mm.

The 20 mm length and 3 mm diameter provide a balance of penetration and holding power in soft and medium-density wood. Supplied in a 200-piece pack, they reduce the need for frequent reordering for small to medium projects and help keep a steady stock for maintenance or production tasks.

How to use

Select an appropriate pilot hole if working with hard or split-prone wood; for softwoods a pilot hole may not be necessary. Position the screw on the driver, align it with the intended fastening point, and drive it straight into the material until the head is flush or slightly countersunk, depending on the application. For precise assemblies, clamp parts together to maintain alignment while fastening. Use a manual screwdriver or compatible power driver at moderate speed to avoid overdriving or stripping the head.

Recommendations

Store the screws in a dry environment to prevent corrosion. For exterior or high-humidity applications, consider using corrosion-resistant fasteners or additional protective coatings. Verify compatibility of screw diameter and length with the materials and fittings to ensure secure connections.
