3.9mm x 16mm Pozi Flange AB Self Tapping Screw BS 4174 | Black Zinc Steel

Where a washer-style head form is helpful, this 3.9mm x 16mm Pozi flange AB screw provides a tidy BS 4174 fastening solution. The black zinc steel construction should be selected to suit the surrounding environment.

The PZ2 Pozi recess helps the installer maintain pressure during driving, while the AB thread form is suited to self tapping into compatible materials. This is particularly useful for assemblies where the screw head remains visible after installation.
