G4.6 ISO B/N GAL
G4.6 ISO B/N GAL refers to a Grade 4.6 ISO-compliant Bolt and Nut set with a Galvanized finish. These fasteners are commonly used in construction and engineering applications where moderate strength and corrosion resistance are required.
These fasteners are made of galvanized steel commonly used in construction and engineering applications where moderate strength and corrosion resistance are required.It offers optimal strength, corrosion resistance, and precision, making it ideal for applications where safety and efficiency are paramount. It comes in a range of sizes named as Number 6,8,10,12,14 based on application needs.

Features of G4.6 ISO B/N GAL
- General-purpose Grade 4.6 bolt and nut set
- Quality and fit consistency
- Galvanisation for corrosion prevention
- Engineering and construction use
Benefits of G4.6 ISO B/N GAL
- Ensures rust resistance in outdoor Australian conditions.
- Excellent for applications of moderate loads
- Great durability across many projects
G4.6 ISO B/N GAL refers to a galvanised hex bolt and nut set:
- G4.6 (Grade 4.6) → standard structural strength bolt (mild steel)
- ISO → made to international standards
- B/N → Bolt & Nut included
- GAL → galvanised coating for rust protection
These bolts are commonly used in fencing, structural steel, retaining walls, and general construction. They come in multiple sizes like M10, M12, M16, etc.
Grade 4.6 bolts are used for general construction and fencing work. They’re strong enough for most standard applications like fixing posts, brackets, and steel components.
Yes, they’re commonly used outdoors. The galvanised coating protects against rust, which is important in Australian weather. For coastal areas, heavier coatings may be recommended.
Yes, for most fencing jobs they are more than sufficient. At Top Class Fences & Gates, we regularly use them for post fixing, brackets, and structural connections.
- 4.6 → standard strength (good for general use)
- 8.8 or higher → high tensile (used for heavy structural or load-bearing work)
For typical fencing, 4.6 is usually the right balance of strength and cost.
