Industrial Grade Galvanized Carbon Steel Fasteners - U-Shaped Pins and Double-Hole Round Head Rivets
Product Overview
Our galvanized carbon steel fasteners are engineered for high strength, corrosion resistance, and durability in demanding mechanical applications. This product line includes U-shaped pins and double-hole round head rivets, designed for secure fastening in construction, automotive, agricultural machinery, and industrial equipment.
Key Features & Benefits
✔ Premium Material
Made from high-carbon steel (Grade 4.8/8.8/10.9) for superior tensile strength.
Zinc galvanized coating (electro or hot-dip) for rust and corrosion resistance.
✔ Precision Manufacturing
CNC-machined for consistent dimensions and tight tolerances (±0.1mm).
Round head design for smooth installation and enhanced load distribution.
Double-hole rivets allow for secure bolting or wiring applications.
✔ Versatile Applications
Construction & Infrastructure – Scaffolding, steel frames, and structural joints.
Automotive & Machinery – Engine components, chassis fastening, and hydraulic systems.
Agricultural Equipment – Tractors, harvesters, and irrigation systems.
General Industrial Use – Conveyor belts, assembly lines, and heavy-duty fixtures.
✔ Customization Options
Available in different diameters (M4–M20) and lengths (10–200mm).
Optional passivation, powder coating, or black oxide finish.
Custom markings (laser engraving, embossing) for traceability.
