5-40 X 3/4 Slotted Fillister Narrow head Machine screw STAINLESS .205 #5 5/40 

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. 

Passivated stainless steel screws provide added protection against oxidation and corrosion.

They have a tall head with a deep drive to maximize driving power and a narrow diameter to fit in tight spaces. 

Length is measured from under the head.
