Key Features

- Double Slotted Design: The slotted head allows for easy installation and removal with slotted screwdrivers.

- Square Nuts Included: Each bolt is supplied with a square nut, providing a secure fit.

- Low Profile Mushroom Head: The design minimizes protrusion, making it ideal for flush applications.

Application and Use

While specifically marketed for roofing, these bolts serve a multitude of purposes in joining products together within various fields. When installing, it is advisable to use clearance drill sizes that are 1mm larger than the bolt diameter for optimal fit and ease of use. This precaution ensures that the bolts can be securely fastened without causing material stress.

Corrosion Resistance

The zinc coating on these bolts plays a crucial role in preventing the oxidation of the protected metal, extending the lifespan of the fasteners. It achieves this by forming a protective barrier while also acting as a sacrificial anode if the coating is compromised. Unlike iron oxide, which can undermine a substrate’s surface integrity, zinc oxide forms a fine white dust that does not lead to deterioration. When maintained, this zinc oxide layer can further shield the bolt from oxidation, akin to the protective qualities seen in aluminium and stainless steels due to their own oxide layers.

Installation Advice

When using slotted screwdrivers to drive these roofing bolts, it is essential to ensure that the screwdriver tip matches the width of the screw slot adequately. An improper fit may lead to damage to the screw head. Slotted screwdrivers are available in two types: flared and parallel. For most applications, a flared tip is recommended; however, if the bolt needs to be driven below the material surface, a parallel tip screwdriver should be employed to achieve the desired finish.
