The flat washer distributes holding pressure and protects delicate surfaces from damage while the split lock washer adds tension to prevent loosening from small amounts of vibration. Also known as Sems screws, the washers rotate freely but are permanently attached. They're made from 316 stainless steel and have good chemical resistance. Screws may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. Length is measured from under the head.
The threads of these Screws are metric coarse threads!
Type of Stainless Steel:
201 Stainless Steel (SUS), suitable for use in a dry environment, it is easy to rust with water.
