Product Description
No.8 4.2mm Black Zinc Plated Steel Pan Pozi Self Tapping Screws
No.8 self tapping screws manufactured from steel with a black zinc plated finish. The pan head provides a raised, rounded profile, while the Pozi recess allows installation using a matching screwdriver or driver bit.
Available in 16mm and 25mm lengths for repairs and general assembly where a black finish is required. The AB type self tapping thread forms a mating thread in a suitably sized pilot hole.
