Industrial Applications
Food Machinery Stainless Steel Fasteners
Food Grade Screws, Nuts, Bolts, Washers, CNC machined parts and Fasteners
High-Performance Food Grade Fasteners for Corrosion-Resistant and Hygienic Equipment
High-performance fasteners are essential in food processing environments, where corrosion resistance, hygiene, and mechanical strength are critical. Exotic alloys like Hastelloy, Inconel, Monel, and titanium resist harsh cleaning chemicals, high-temperature steam, and acidic or saline foods, ensuring durability in mixing, fermenting, and packaging lines. Their resistance to pitting and stress-corrosion cracking reduces maintenance and downtime while supporting compliance with FDA and USDA standards.
Welle Fasteners, with over 20 years of experience, supplies reliable, application-specific fastening solutions for global food and beverage processing industries, delivering cost-effective systems designed for demanding equipment environments.

Fastener Material Solutions for Food Industry Applications

A2-70 Stainless Steel for Food Industry Applications
Type 304 stainless steel, part of the 18-8 austenitic family, is the most widely used grade in food processing. It offers excellent resistance to organic acids found in fruits, meat, milk, and vegetables, making it ideal for sinks, countertops, cooking equipment, storage tanks, and processing machinery. It is widely applied in bakeries, mills, and meat processing plants, especially where exposure to oils, fats, and mild acids is common.

A4-70/A4-80 Stainless Steel for Harsh and Corrosive Environments
Type 316 stainless steel is designed for demanding environments requiring higher corrosion resistance. With molybdenum to resist chlorides and industrial chemicals, it performs well against brines, hypochlorite solutions, and acids used in food processing. It is ideal for areas with frequent washdowns, as well as marine and medical applications where durability and corrosion resistance are critical.

Specialty Materials for Demanding Food Processing Applications
In addition to 304 and 316 stainless steel, food processing equipment may require specialized materials for unique operating conditions. Duplex 2205 stainless steel combines superior corrosion resistance with exceptional strength, making it ideal for seafood processing, salt-rich environments, and aggressive washdown conditions. Hastelloy® C276 provides outstanding resistance to acids, chlorides, and harsh cleaning chemicals, making it the preferred choice for extreme chemical processing environments. Engineering plastics such as PEEK, PTFE, and Nylon provide excellent chemical resistance, electrical insulation, and hygienic performance, making them suitable for spacers, bushings, washers, and specialized food-grade components. These materials enable manufacturers to optimize durability, hygiene, and long-term reliability across a wide range of food processing applications.
