This box of stainless steel countersunk screws is supplied in a 4.0 x 40mm size and a pack quantity of 200. Manufactured from A4 marine grade stainless steel, these screws are commonly chosen for installation tasks in environments exposed to moisture, salt air, or other corrosive factors.
Frequently used by joiners, carpenters, and builders, these screws are suitable for fixing softwoods, hardwoods (when pre-drilled), chipboard, MDF and certain plastics. They are often selected for outdoor joinery, decking, or general construction, particularly in coastal locations or with materials known to be naturally corrosive, such as green oak.
