Product Description
No.8 A2 stainless steel pan slotted self-tapping screws manufactured to DIN 7971, available in imperial lengths from 3/8" to 1".
These Type AB self-tapping screws feature a pan head, traditional slotted drive and sharp self-tapping point. The thread forms a mating thread as the screw is installed into a correctly sized pilot hole in suitable sheet materials, plastics and other compatible components.

Pan slotted self-tapping screws are commonly used for fixing panels, covers, brackets, electrical equipment, appliances, instrument components, machinery and general engineering assemblies.
The pan head provides a broad bearing surface above the material, while the traditional slotted drive allows installation using a correctly sized flat-blade screwdriver.
Type AB self-tapping screws combine a fine tapping thread with a sharp point. A correctly sized pilot hole is normally required, with the suitable diameter depending on the material type, hardness and thickness.
A2 stainless steel provides good general corrosion resistance for indoor and outdoor applications. For marine, coastal, swimming-pool or highly corrosive environments, A4 stainless steel may be more suitable.
These screws are self-tapping rather than self-drilling. A pilot hole is therefore normally required, particularly when installing into metal or other hard materials.
For pan head screws, the length is measured from beneath the head to the end of the point.
Please note: Specifications and dimensions are intended as a guide only. Pilot-hole requirements and suitability depend on the material being fixed. If dimensions or application requirements are critical, please check with us before ordering.
