Sealing Hex Head Screws
An O-ring under the head prevents leaks and seals out contaminants. Made of silicone, the O-ring withstands salt water, most acids, and temperatures up to 400° F. These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They are reusable. Length is measured from under the head.
Replacement silicone O-rings are sold separately. Choose fluoroelastomer O-rings when you need oil and chemical resistance.

Sanitary Hex Head Screws


Bolt down equipment in food processing or sanitary areas while sealing out contaminants. Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these screws have a nitrile rubber seal underneath the head to keep liquid and debris off the threads and prevent an unsanitary metal-to-metal connection. 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 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.

Steel Drilling Screws with Washer for Metal

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments.
Corrosion-resistant-coated steel screws are more corrosion resistant than zinc-plated screws.

Stainless Steel Vibration-Damping Hex Head Screws for Sheet Metal

Made from 18-8 stainless steel, these screws are chemical resistant and may be mildly magnetic. A rubber washer cushions the screw to resist loosening from vibration. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the washer.

Screws for Joining Sheet Metal to Wood

Able to penetrate overlapping sheets, these screws have a secure hold in wood. The hex head allows for a firm grip with a wrench, while a rubber washer provides a watertight seal. They're corrosion-resistant-coated steel to resist corrosion in wet environments and minimize reactions between dissimilar metals. Length is measured from under the washer.
