Metal Self Drilling Countersunk Wing Screws - Class 3
The specially designed wings on these SDS CSK screws will cut a clearance hole in timber.
As the SDS point drills through the steel sheet, the wings break off, the thread is formed
and the timber is secured, all without the need for predrilling.
Strong 6 Nibs for self embedding into timber. The six ribs design will ream through light cement sheeting, chipboard and timber, allowing the head to sit below the surface, facilitating easy filling.
