Hygienic fasteners are specially designed for use in sanitary and clean-process environments where hygiene, corrosion resistance, and easy cleanability are essential. Manufactured from high-quality stainless steel with a smooth polished silver finish, these fasteners minimize dirt traps and support effective cleaning and sterilization.

As shown in the image, the range includes hex bolts, hex nuts, dome (acorn) nuts, and studs, suitable for hygienic equipment assembly and stainless-steel installations.

Product Overview

Hygienic stainless steel fasteners are used for secure and reliable fastening of equipment, pipe supports, frames, and enclosures in food, beverage, pharmaceutical, and biotechnology industries. The smooth surface finish and precision machining ensure excellent resistance to corrosion, chemicals, and frequent wash-down conditions.

Dome nuts are used where exposed threads must be covered, improving safety and hygiene by eliminating sharp edges and contamination points.
