Stainless Steel Pan Head Screws with External-Tooth Lock Washer
1. Description:
These stainless steel screws have good chemical resistance and may be mildly magnetic. They’re passivated for added protection against oxidation and corrosion. All have a washer with sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached. Length is measured from under the head.
