Metal-Detectable Threaded-Stud Knobs

Made for use in food processing facilities, these plastic knobs have a metal additive that sets off metal detectors if a piece breaks off into your line. They’re also bright blue, so it’s easy to find and retrieve loose pieces. They help you comply with Hazard Analysis and Critical Control Point (HACCP) programs for keeping contaminated food from leaving your facility.
These knobs give you a secure grip to tighten, position, and hold components in place. Made from nylon, they’re wear resistant and won’t degrade from oil, grease, and solvents. They meet ISO 4753 standards for the ends of threaded parts, and they’re FDA compliant for direct food contact. Mount them into a threaded hole.

Sanitary Threaded-Hole Knobs


Designed for sanitary environments, these knobs are commonly used in pharmaceutical and food-processing facilities. Install them on threaded studs to position, tighten, and hold equipment. The Buna-N rubber seal keeps out contaminants and blocks unhygienic metal-to-metal contact. The seal is blue, making it easy to spot and remove if it falls into your line. It’s also FDA compliant for direct contact with food. These knobs have a 316 stainless steel body that resists corrosion from frequent washdowns with harsh cleaners. Highly polished, with rounded edges and no horizontal ledges, they have no crevices where bacteria can grow.

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.

Metal-Detectable Threaded-Hole Pull Handles

Open and close a variety of doors and drawers on machines and equipment next to food processing lines while reducing the risk of contaminating the food. To help you comply with Hazard Analysis and Critical Control Point (HACCP) programs for food safety, these handles contain metal additives that will set off metal detectors. They’re also bright blue, making them easy to spot if they fall into your line. All are FDA compliant for direct contact with food.
Made of nylon, these handles resist wear and repel oil, grease, and solvents. Their rectangular grip has a flat surface that keeps your hand from slipping. Thread screws through holes from the back of your surface into the handles to install them.

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 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.
