Dufresne Standard & Special are experts in all kinds of nuts and bolts. We manufacture or modify up to 6'' in diameter or according to your specifications. With an inventory of more than 40,000 different products, we are sure to find a way to meet your needs. As the name suggests, our company is known for its work with specialized as well as standard nuts and bolts.


Founded in 1989 in a small store in St-Michel, Dufresne Standard & Special has managed to carve out a prominent place in the industrial sector. After a few years in the business, we opened a second building in 1995 and a third in 2000, which provided more storage space for nuts and bolts. Renowned for our expertise and fast service, our clientele has only continued to grow.

For the past 30 years, we have amassed a large inventory that enables us to respond very quickly to customer requests. We are used to dealing with special requests, such as stainless steel (304,316.410.Monel, Inconel, 17-4 PH and several other types of non-ferrous steel), carbon steel, alloy steel and all kinds of plating using imperial, metric, British and even pipe sizes. No matter the industry in which you operate, we have the nuts and bolts you need.

Boulons Dufresne

All of our inventory is now compliant with RoHS standards. In addition, every order is eligible for free same-day delivery in the greater Montréal area or can be picked up within 30 minutes. Run by two brothers, our family business works tirelessly to provide the best possible service to better meet your needs. The members of our team prefer sharing their expertise in person to address each customer's individual needs.
