Tex Screws For Timber To Steel Countersunk
Specifically designed to attach wood to metal (Max 3mm). Coarse self-tapping thread with wings designed to ream out the timber, so the screw can achieve Max R.P.M. without burning out. When the wings hit the metal they will break off to permit the thread to self-tap into the metal. A bright zinc electrolytic plating with a clear toxin free finish.
