Self Drilling Countersunk Wing - Coarse Thread
Self drilling countersunk wing tek screws are ideal for fixing timber to steel without the need to pre-drill. These screws have a hardened steel self drilling point (tek point) which cuts through mild steel without the need for pre-drilling (see product attributes for material thickness constraints). The two protruding wings create clearance through the timber and break off during entry into the steel. The aggressive self embedding head means this screw can be quickly applied without the need to pre-drill or countersink, saving loads of time during application.
