Stainless Steel Bolts in Toronto & the GTA
316 and 18-8 stainless hex, carriage, lag, socket head and flange bolts, plus threaded rod, for construction, fabrication and industrial work across the GTA.
Corrosion-Proof Connections That Hold.
Stainless bolts carry structural and mechanical loads where plain or zinc-plated steel would rust out — exterior steel, railings, docks, food and process equipment, and anything exposed to salt.
We supply imperial and metric stainless bolts in full and partial thread, matched with the nuts and washers to complete the assembly.

Which Grade For Your Bolt?
| Grade | Corrosion Resistance | Best For |
|---|---|---|
| 18-8 / 304 | Good | General exterior structural and mechanical connections |
| 316 | Excellent — chloride resistant | Marine, lakefront, road-salt exposure, railings, food and chemical environments |
Where It Gets Used
- Structural steel and exterior connections
- Railings, balconies and guards
- Docks, marinas and lakefront structures
- Food, beverage and process equipment
- Decks, timber framing and fences
Spec It Right
- Stainless is not a direct substitute for high-strength structural bolts — confirm the required strength with your engineer
- Pair 316 bolts with 316 nuts and washers; mixing grades lowers corrosion performance
- Apply anti-seize to prevent thread galling, especially on larger diameters
- Specify full or partial thread based on the shear plane
