TERF® M8 X 100mm Coach Screws Hex Head M8 (8mm) X 100mm Wood Masonry Brick Concrete Wall Fixing Lag Screw Bolts for Aerial Satellite Dish TV Bracket Fence Shelves Mounting Decking - Pack of 10

I like these. Quality is good. They screw in nicely and grip well. I did drill pilot holes for them as they did have a tendency to split narrow timber or if you get too close to the edge of wider timber. If you drill a pilot hole even if it's not all the way through they will go in easier without causing splitting They will go through an undrilled 75 x 75mm fence posts without splitting but you will need quite a powerful drill to drive them in. Overall they are good value for money and did exactly what I needed them to do.

Used to bolt structural timbers to a retaining wall for holding heavy 8mm glass panels. Job done and all seems good and solid!

Good bolts

Good quality, smooth thread.

Great price and quality

These did the job, quality product, recommended.

Bolt sheared, I'm never getting the rest out of the floor and will have to move my toilet now. An easy job has been made much harder. Will bin the rest of these, poor quality metal.

I have been trying to attach a smallish log splitter to a stump to use to make kindling. It takes a good bit of punishment splitting some of the logs with knots in. The bolts/screws I have been using have all corroded or snapped after a couple of weeks. These are very strong and well made and tightened down really well. I have used it a good few times now and the Splitter is still attached securely and doesn't look or feel like it's going to move any time soon. Defo recommended..
