What is a Thunderbolt™?
A thunderbolt is a heavy-duty self-tapping anchor designed for concrete, brick, block, stone, and wood. It creates a strong hold, making it essential for the construction industry.
Also known as
Concrete bolts or masonry bolts.
Why use Thunderbolts?
Thunderbolts give you a quick way to fix materials together. Unlike through bolts and sleeve anchors, they don’t expand, so you can:
- Fix close to the edge of your material, such as a wall – No risk of cracking weak sections
- Avoid stress on the material – Drill and screw in without expansion pressure
- Remove and reuse – They unscrew cleanly
- Save time on-site – Just drill, screw, and tighten
- Get a neat finish – No bulky fixings sticking out
Thunderbolts: How they work
Drill a hole into concrete or brick, clear out dust and debris, then simply screw in the Thunderbolt and tighten.
