Stainless Steel Pan Head Screws with Spring Washer 2 IN 1 Pan Head
SEMS Screws
Products Descriptions
Made from stainless steel, these screws have good chemical
resistance and may be mildly magnetic. They have a split lock
washer that flattens as the screw is tightened to add tension and
prevent loosening from small amounts of vibration. Also known as
Sems screws, the washer rotates freely but is permanently attached.
They're passivated for added protection against oxidation and
corrosion. Length is measured from under the head.
