Used 10mm drill bit into the post and an 8mm drill bit into the masonry and it worked a treat. ### ⭐⭐⭐⭐⭐ Great bolts *by L***M on 6 September 2022* I used the bolt to affix some wooden posts to brick work, they were easy to use just drill the right size hole and screw in they have been sturdy all summer long and are still holding my gate up cannot be happier ### ⭐⭐⭐⭐⭐ Rock solid fixings *by T***R on 6 April 2020* I bought these bolts to hang a punch bag/pull up bar onto a brick garage wall. The bolts included with the bracket proved woefully inadequate. These Thunderbolt's are incredible, they provide a VERY strong bond, the deep threads cutting into the brick and they require no plugs ect. Be sure to use a 8mm drill bit for the pilot hole and a ratchet to screw the bolts in, this requires some effort! ## Frequently Bought Together - 8, M8 x 100 Genuine Thunderbolt® Masonry Concrete Anchor Screw with Hexagonal Head (V35157) - M8 Penny Repair Washers (20 PACK) 8.4mm x 25mm A2 Stainless Steel Large Flat Repair Washer Free UK Delivery - 8, M8 x 75 Genuine Thunderbolt Masonry Concrete Anchor Screw with Hexagonal Head (V35156) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/67184361-8-m8-x-100-genuine-thunderbolt-masonry-concrete-anchor-screw](https://www.desertcart.com.ar/products/67184361-8-m8-x-100-genuine-thunderbolt-masonry-concrete-anchor-screw) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-13*
