Bolt down equipment in food processing or sanitary areas while keeping out contaminants. These screws have a rubber seal underneath the head that keeps liquid and debris off the threads and prevents an unsanitary metal-to-metal connection. They’re certified by the European Hygienic Engineering and Design Group (EHEDG) to meet sanitary design standards. The seal is also FDA compliant, so it’s safe for direct contact with food.

Made from 316 stainless steel, these screws won’t corrode from frequent washdowns with water or harsh cleaners. They may be mildly magnetic. They have self-draining surfaces, which means there are no horizontal ledges, so liquid and debris will drain off completely. The smooth, polished sides and rounded edges have no pits or crevices where bacteria could grow.

All seals are made with chemical additives, so they’ll show up on an X-ray machine if they fall into your line. Buna-N seals also have metal additives that will set off metal detectors.
