Sanitary Extra-Wide Truss Head Screws
Designed for use in food, pharmaceutical, and other sanitary environments, these screws have an extra-wide truss head that distributes holding pressure to reduce the likelihood of crushing thin materials. All are made from stainless steel, so they won’t corrode from frequent washdowns with harsh cleaners and sanitizers. These screws have an extremely smooth 32 Ra finish and are self-draining to reduce the risk of bacteria growth. They also have wrench flats for damage-free tightening and loosening with a spanner wrench. Length is measured from under the head.

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.

Sanitary Spade-Head Thumb Screws
Fasten material by hand, so tools don’t scratch or contaminate parts you frequently adjust in food-processing or pharmaceutical plants. Made from 316 stainless steel, these thumb 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 food will run off completely. The smooth, polished sides and rounded edges minimize spots where bacteria could grow.

Sanitary Threaded Standoffs
Mount components onto food processing lines, walls, and sanitary equipment while leaving space to clean in between. These standoffs have a smooth finish and rounded edges to eliminate pits or crevices where bacteria could grow. Made of 304 stainless steel, they won’t corrode from frequent washdowns with harsh cleaners and sanitizers. A rubber seal stops water and contaminants from entering the body of these standoffs. They are FDA compliant for safe contact with food.
Standoffs with a locknut and washer can be mounted to an enclosure.

Sanitary Twist-to-Lock Knob-Style Retractable Spring Plungers
Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position. All of these plungers have a long nose that offers a large bearing surface to handle side loads. They’re often used for maintenance jobs.
Made of stainless steel, these plungers won’t corrode from frequent washdowns with harsh cleaners and sanitizers. All are self-draining with rounded edges and polished surfaces, so there are no crevices for bacteria to grow, reducing the chance of a foodborne illness. Seals block out water and keep contaminants from getting trapped in threads or grooves. They’re also bright blue, so you can easily spot broken pieces that fall into your line. The seals are FDA compliant for direct contact with food, but the lubricant is rated for incidental contact.
Spring plungers with a sealing nut can be held in place with the nut after threading them to your desired depth. The nut completely covers the threads and has two seals to block out water and other contaminants.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Sanitary Threaded-Stud Pull Knobs
Thread these sanitary knobs into holes so you can open doors and drawers in hygienic environments. They’re commonly used on furniture and equipment in pharmaceutical and food-processing facilities. Made of Buna-N rubber, the seal keeps out contaminants and blocks unhygienic metal-to-metal contact. It’s FDA compliant for direct contact with food, and blue for easy spotting and removal if it falls into your line. Knobs have a 316 stainless steel body, so they resist corrosion from frequent washdowns with harsh cleaners. Highly polished, with rounded edges and no horizontal ledges, they leave no room for bacteria to grow.

Sanitary Threaded-Hole Pull Knobs
With a sanitary design, these threaded-hole knobs are often used to open and close doors and drawers on furniture, machines, and other equipment in pharmaceutical and food-processing facilities. They attach like most knobs in your kitchen—push a screw through the back of a hole and thread these knobs onto the front. The seal is blue, so it’s easily seen and removed if it falls into your line. It’s also FDA compliant for direct contact with food. Knobs have a 316 stainless steel body that resists corrosion from frequent washdowns with harsh cleaners. They’re highly polished with rounded edges and no horizontal ledges, leaving no room for bacteria to grow.
