Product Description
No.8 A2 stainless steel countersunk Pozi head self-drilling Tek screws, available in imperial lengths from 1/2" to 1 1/2".
These screws feature a countersunk head that sits flush in a correctly prepared countersunk hole, together with a Pozi drive for positive screwdriver engagement. The drill-point tip is designed to form its own pilot hole in suitable softer materials, helping to reduce the need for separate drilling and tapping operations.

These self-drilling screws are suitable for fixing panels, brackets, trims, covers, plastic components, aluminium sheet and other light-duty assemblies where a flush-fitting screw head is required.
A2 stainless steel provides good corrosion resistance for general indoor and outdoor applications. For marine, coastal, swimming-pool or highly corrosive environments, A4 stainless steel may be more suitable.
Please note: These screws do not self-drill into steel. They are intended for use in wood, plastic or aluminium. Suitability will depend on the thickness and hardness of the material being fixed.
For countersunk screws, the length is measured overall from the top of the head to the end of the drill point.
