Product Description
No.4 2.9mm A4 Stainless Steel Pan Pozi Self Tapping Screws
These No.4 A4 stainless steel pan head self tapping screws feature a Pozi drive and a nominal thread diameter of 2.9mm. Their rounded pan head provides a broad bearing surface and sits above the material after installation.
A4 stainless steel offers excellent corrosion resistance, making these screws a useful choice for outdoor, coastal and marine fittings where the material is suitable for the application. The self tapping thread forms a mating thread in a correctly sized pilot hole.
