To achieve the best results, use a 3mm hex key for installation. If installing into wood, it is critical to pre-drill a pilot hole and use a countersink bit that matches the 10mm head diameter to ensure the screw head seats properly. For metal applications, ensure the material is tapped to the correct M5 thread pitch to avoid stripping. To maintain the life of the fasteners, keep them in a dry environment to prevent oxidation and ensure the hex socket remains free of debris for consistent tool engagement.
