ROOFING BOLT & NUT

More info

Roofing Bolt & Nut (RBN)

This is a standard Roofing Bolt and Square Nut set, typically used in construction and general DIY for fastening thin materials like corrugated roofing sheets, cable trays, and fencing.

Key Features

Large Mushroom Head: The broad, low-profile head (also known as a truss head) provides a larger surface area, which helps prevent the bolt from pulling through thin or brittle materials.
Cross-Recess (Phillips) Drive: Designed for easy installation with a standard screwdriver or power tool.
Square Nut: The included square nut provides a greater surface contact area than a standard hex nut, offering better resistance to loosening in vibrating environments or against soft materials.
Zinc Plated Finish: Most commonly supplied with a bright zinc plating (BZP) to provide a layer of corrosion and rust resistance, suitable for indoor and light outdoor use.
