Forgefix Lightning Bolts, Hex Head - M12 x 200mm - Multicolor

The primary advantage is their self-threading design, which allows for quick and easy installation directly into a pre-drilled hole without the need for a sleeve or plug.

Yes, the unique thread design of these bolts anchors along their total length, making them suitable for hollow brick or block applications as well as solid masonry.

The 'Elementech' coating provides superior anti-corrosion resistance, tested to withstand 1,000 hours in a salt spray environment, ensuring durability and longevity of the fixing.

You will need a drill to create the pilot hole and an appropriate wrench (such as a socket wrench) to drive the hex head bolt into the substrate.

They are suitable for most masonry substrates including concrete, brickwork, and hollow block or bricks.

These bolts provide a high load capacity for general fixing applications like battens, handrails, and racking. For specific structural applications, consult engineering guidelines and product load data.

Over-tightening can strip the threads in the base material, leading to a loose fixing. It's important to tighten until secure but not forcefully.

Verify the pilot hole diameter and depth are correct for the substrate and bolt size. Ensure the hole is clean and free from debris.

The pilot hole may be too large, or the substrate material might be too soft or crumbly. Consider a larger diameter bolt or a different fixing type if the substrate is compromised.

While the 'Elementech' coating offers superior protection, extreme environmental conditions could eventually impact it. Ensure storage is in a dry place. For critical applications, inspect periodically.

This usually occurs from over-tightening or using an incorrect pilot hole size. Remove the bolt and re-drill with the correct dimensions, or use a slightly larger pilot hole if the material allows, and install a new bolt carefully.
