Stainless Steel Hexagon Bolt with Spring and Plain Washer Hex Head SEMS Screws
Products Descriptions
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 18-8 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.
