Unlike traditional expansion anchors, the Thunderbolt features a patented concave thread that cuts its own thread into concrete, brick, stone, and block, creating a secure fixing with exceptional pull-out resistance. The non-expansion design prevents stress or cracking in the substrate, making it ideal for use in both solid and brittle materials. The hexagonal head allows for high torque installation with standard spanners or sockets, ensuring a fast and efficient fixing process. Fully adjustable and removable, the Thunderbolt offers flexibility for repositioning or reuse without compromising performance. Perfect for fixing timber beams, steel plates, brackets, fencing, railings, racking, heavy machinery, and structural applications, this anchor screw delivers unmatched strength and durability. Review: Easy to use, strong and secure for fixings - Bought these to fix metal footings for fence posts into the top of a wall, for an existing fence that took a battering from recent gales. Took a bit of research to make sure I used the correct drill bit size (tip: it’s 8mm for an M8) so that the bolts would grip into the bricks like they are designed to do. I used a ratchet to screw the bolts into the bricks, this gives the torque needed to carve the thread into the bricks and actually was quite easy to do. Another tip is to make sure you keep the drill straight when drilling the hole and make sure the bolt is straight as it starts to screw in, otherwise it can be a bit stiff. I was worried the bolts might split the bricks, but all went ok and they worked just as they should. Nice and sturdy, and the fixings mean our fence posts are securely fixed now. Would definitely recommend thunderbolts, easy to use and strong. Review: Perfect! - Exactly what I needed to attach a new gate post to a brick wall. Easy to install, just drill a slightly smaller hole than the bolt and ratchet it in, I used 4, they worked perfectly for me! Great quality, speedy delivery and great price. ## Features - Hexagonal Head Design – Provides maximum grip and torque transfer, ensuring fast, reliable installation with standard spanners or sockets. - Non-Expansion Technology – Stress-free fixing that won’t crack or damage the substrate, unlike traditional expansion anchors. - Self-Threading Action – Patented concave thread design cuts its own thread into the base material for superior pull-out resistance. - Adjustable & Removable – Can be unscrewed and re-positioned without loss of performance, allowing precise and flexible fixing. - Versatile Applications – Ideal for fixing timber, metal plates, brackets, railings, racking, and heavy equipment into solid masonry. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01721FGRG | | Best Sellers Rank | 222,766 in DIY & Tools ( See Top 100 in DIY & Tools ) 2,338 in Screws (DIY & Tools) | | Brand Name | AeapYar | | Compatible Groove Diameter | 8 Millimeters | | Customer Reviews | 4.5 4.5 out of 5 stars (331) | | Drive System | External Hex | | Exterior Finish | Yellow Zinc | | Fastener Size | M8 | | Fastener Type | Hexagonal Bolt | | Finish Types | Unfinished | | Grade Rating | Grade 8 | | Head Type | Sześciokątny | | Item Diameter | 8 Millimetres | | Item Hardness | Grade 10.9 | | Manufacturer | GENUINE THUNDERBOLT® | | Manufacturer Grade | Grade 8 | | Material Type | Alloy Steel, Zinc | | Metal | Alloy Steel | | Number of Pieces | 1 | | Screw Head Style | Hex | | Set Name | 1 | | Set Screw Thread Type | Metric | | Size | M8 | | Thread Coverage | Fully Threaded | | Thread Size | M8 | | Thread Style | M8 | | Thread Type | Metric | | Unit Count | 8 Count | ## Product Details - **Exterior finish:** Yellow Zinc - **Head style:** Hex - **Manufacturer grade:** Grade 8 - **Material:** Alloy Steel, Zinc - **Thread size:** M8 ## Images ![8, M8 x 150 Genuine Thunderbolt® Masonry Concrete Anchor Screw with Hexagonal Head (V35159) - Image 1](https://m.media-amazon.com/images/I/81jylcmTnZL.jpg) ## Questions & Answers **Q: What size hex driver do you need for an M8 thunderbolt** A: sorry can't help as I used an adjustable spanner. I know its not a metric size **Q: What size socket do I need to tighten them** A: 15mm socket **Q: I have m8 150mm long bolts is it right that the thread doesnt go right to the top of the hexagonal bolt end** A: Depends on what you’re fixing to the wall. If the item you’re fixing is as thick as the part of the bolt missing the thread then no issue. The thread is there to cut into the brick only. **Q: can you advise on the price for 10 bolts** A: Good value and very secure ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use, strong and secure for fixings *by N***S on 26 May 2021* Bought these to fix metal footings for fence posts into the top of a wall, for an existing fence that took a battering from recent gales.
