Self drilling pozi countersunk wing screws DIN 7504P. They can bore straignt into wooden floor boards and the wings break-off as the screw drill bit hits the metal without the need to pre-drill saving time.
It is important to get the correct tensile strength using the correct self drilling tek screw diameter and length to provide a secure fixing.
These are bright zinc plated fasteners which is a preventative measure from corrosion. Ideal for using outdoors or in damp or wet environments. Also bear in mind using different materials can cause fusing through corrosion especially in damp conditions when mixed with aluminium or stainless steel materials.
