With an O-ring under the head, these screws seal out leaks and contaminants while also preventing unwanted removal. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Screws are passivated for added protection against oxidation and corrosion.
Silicone O-rings are good for a wide range of temperatures and resist corrosion from salt water.
Special types available on request.
