Product Overview
The Screw M4 x 16 Flat Head Posidrive A-4 Stainless Steel Type 316 are flathead Pozidriv screws that are different from normal screw heads. Pozidriv screws have a set of radial indentations set at 45° from the main cross recess on the head of the screw. This prevents the screwdriver from popping out of the screw and damaging the head. A Pozidriv screwdriver has parallel flanks, a blunt tip, and additional smaller ribs at 45° to the main slots. Pozidriv screw allow more torque to be applied. This screw is made of a type 316 stainless steel, it has significantly improved corrosion resistance, especially when exposed to seawater and many types of chemicals. They contain molybdenum, which gives the steel better resistance to surface pitting. These steels have higher tensile and creep strength at elevated temperatures than other austenitic alloys. Stainless steel also maintains excellent toughness. This type of screw is used in Aisys series anesthesia machines.
