Dewalt (DWF4020008) 500 x SD Screw 62x5.5mm Countersunk Head with Point Wings

Product Overview:

• The screws feature a point that will self drill and thread without the need for pre-drilling.
• Depending on the gauge, thread pitch, thickness of material and application, these screws will drill through steel up to 4.0mm.
• The clever wings on these countersunk head screws, drills a clearance hole in timber.
• This prevents the timber from rising up as the screw penetrates the metal, and negates the need for pre-drilling.
• As the screw point drills through the metal base material, the wings break off, the thread is formed and the head clamps down to secure the timber.

Features:

• Self drilling screws for metal profiles.
• Additional wings for clearance hole drilling in timber.
