Stainless Steel Nuts & Washers in Toronto & the GTA
316 and 18-8 stainless hex, nylon-insert lock, flange, cap and coupling nuts, plus flat, fender, lock and sealing washers for GTA contractors and fabricators.
Complete The Assembly In The Same Grade.
A 316 bolt with a plated nut is a 316 job with a rust problem. Nuts and washers have to match the bolt grade, or the weakest part of the connection fails first.
We supply stainless nuts and washers in imperial and metric to complete every bolt, screw and anchor we sell.
