Product Description
No.8 A2 stainless steel hexagon-head self-tapping screws manufactured to DIN 7976, available in imperial lengths from 3/8" to 2".
These Type AB self-tapping screws feature an external hexagon head and sharp self-tapping point. The screw forms a mating thread as it is installed into a correctly sized pilot hole in suitable sheet metal, plastics and other compatible materials.

Hexagon-head self-tapping screws are commonly used for securing sheet-metal panels, brackets, covers, ducting, electrical equipment, automotive components, appliances, machinery and general engineering assemblies.
The external hexagon head allows installation using a correctly sized socket or nut spinner. This provides positive tool engagement and can offer better torque transmission than conventional slotted or cross-recessed drives.
Type AB self-tapping screws combine a relatively fine tapping thread with a sharp point. They form a mating thread as they are driven into a correctly sized pilot hole in suitable sheet metal, plastics and other compatible materials.
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 correctly sized pilot hole is normally required, particularly when installing into steel, stainless steel or other hard materials.
For hexagon-head screws, the length is measured from beneath the head to the end of the point.
Please note: The 3/8" length is available in the product selector but is not individually shown in the current dimensional table. Its metric length is therefore provided as an approximate conversion. Specifications and dimensions are intended as a guide only. Pilot-hole requirements depend on the material type, hardness and thickness. If dimensions or application requirements are critical, please check with us before ordering.
