I am about to erect a replacement wooden fence (as soon as it arives, in a
week or so). It's going onto an existing concrete base (driveway) so I think I'll be using bolt-down metposts or similar. The curved-top fence panels are 3 feet high at the ends and 4 feet high in the centre and the total run is 18 feet, 3 panels. I know I should use rawlbolts or similar but what size? The metpost leaflet just says M8X10mm, no indication of the length of the bolt. Also, although I am a bit "iffy" about using Screwfix at the moment (series of upcocks on their part) would their "sheild anchors" do the job, they seem a lot cheaper than rawlbolts. Grateful for any advice Bob |

Hi Bob
Also, although I am a bit "iffy" about using Screwfix at the moment (series of upcocks on their part) would their "sheild anchors" do the job, they seem a lot cheaper than rawlbolts. They seem to be the same thing to me. Rawlbolts is just a trade name I think. With 4 per post I can't see they would need to be that long, 90mm seems fine to me. Dave |

Shield Anchor Bolts would be fine. A 3ft fence doesn't take too much securing so around 3ins (65-75mm) length will suffice. You'll need a decent hammer drill if you're drilling into concrete. riccip |

Spoilt rotten t'be sure. :-) A decent hammer drill will manage concrete okay, so long as you resist the temptation to buy Chinese masonry bits. How do you reckon we managed in the dark ages before SDS? riccip |

Try using the new screw in bolts not sure what screw fix calls them but
they work really well and are very reliable. |

I've used SDS drills but found they tend to bulldoze through rather than drill accurately. Especially in brickwork. I prefer a big old "pro" hammer drill bought for 6 quid at a car boot sale, came with a box of proper masonry bits. Used it to damp-proof my last house (injection method) and it refused to burn out. riccip |

I've often wondered about them. BTW it claims they are great in cracked and uncracked concrete - what on earth is that? Is it just as it seems - concrete that has cracked? Dave |
