As the sign in the front window says, the public is welcome. The Dundas Fastenal (just south of Northfield on Hwy 3) is a branch of a great industrial supplier of fasteners and tools, but the company want everybody to have access to its products and service. You will find pneumatic, power and hand tools, abrasives, chemicals, paint, metal supplies, hydraulic and pneumatic components, welding supplies and perhaps most importantly safety supplies. Brand names include Makita and Milwaukee Tool.
