The Forgefix M8 x 100mm Lightning Bolts are designed for construction professionals and DIY enthusiasts who need a reliable, high-strength solution for masonry fixings. These bolts provide a stress-free anchoring method that is perfect for close-to-edge installations, though they require precise pre-drilling of holes to ensure the self-threading mechanism performs correctly.

Yes, the thread design allows for effective anchoring along the full length of the bolt in hollow masonry.
No, these are self-threading bolts that anchor directly into the masonry substrate.
They feature an Elementech coating tested to 1,000 hours of salt spray resistance.
They are designed for permanent installation and are generally not intended for reuse after removal.
Yes, they provide high load capacity, making them suitable for holding down machinery and racking systems.
Ensure the pilot hole diameter is correct; if the hole is too large, the threads cannot interlock with the masonry.
Check that the pilot hole is deep enough to accommodate the full 100mm length and clear out all masonry dust.
To install, always drill a pilot hole into the masonry that matches the manufacturer-specified diameter for the M8 bolt. Ensure the hole is cleared of dust and debris using a brush or vacuum to allow the thread to cut effectively. Use an appropriate socket or impact driver to drive the bolt until the head is flush against the fixture. Do not over-tighten, as this may strip the thread in the masonry. Store in a dry place to maintain the integrity of the Elementech coating.
