GALVANISED SET SCREW GRADE 8.8 METRIC

Galvanised grade 8.8 metric hex set screws are fully threaded, high-tensile steel fasteners with a corrosion-resistant zinc coating. They are used for heavy-duty, high-load, outdoor applications such as industrial machinery, structural steel construction, mining equipment, and harsh environment, outdoor infrastructure.

Key Uses and Features:
High-Tensile Strength: Grade 8.8, made from medium carbon steel, provides a tensile strength of 800 MPA suitable for machinery, automotive chassis, and structural applications where high load support is required.
Corrosion Resistance: The hot-dip galvanised (HDG) coating provides a thick, protective layer against rust, making them ideal for outdoor, marine, and wet environments, including coastal areas.
Fully Threaded Design: Because they are threaded up to the head, they are designed to fit into tapped holes or for clamping, providing versatile assembly in tight spaces or where a specific clamping length is not available.
Typical Applications: Used heavily in construction steelwork, commercial fencing, agricultural machinery, trailers, and outdoor electrical infrastructure.

Why They Are Used:
Durability: Combining the strength of 8.8 steel with the protection of zinc, they offer both structural integrity and long life.
Reliability: These are standard, reliable fasteners for machinery that requires resistance to vibration.
