Metric Flange Nuts/Collar Nuts

Rettig’s is your go-to supplier of bulk metric flange nuts and other high-quality industrial supplies.  Flange nuts, also known as collar nuts, spread their fastening force over a wider area, essentially distributing their load like a washer.  The design of these nuts assists in preventing damage to the surface they are being mounted to. 
Our knowledgeable staff is technically trained and able to work with your complex supply list to find the best solution for your industrial application. We have the in-stock inventory to stock any jobsite with bulk orders at wholesale prices, from fasteners to valves and beyond.
